AB  - The is work presents the development of a flow injection system for differential pulse amperometry (DPA) for diazepam determination in the presence of oxygen. The thin flow cell consisted of the bare glassy carbon electrode, reference silver/silver chloride, and stainless steel as the auxiliary electrode. Electrochemical reduction of diazepam (DZP) was characterised by cyclic voltammetry. Azomethine reduction peak was used for DZP quantification. The detector response was linear in the range 20-250 mu mol/dm(3) of diazepam, with a calculated detection limit of 3.83 mu g/cm(3). Intraday and interday precision were 1.53 and 10.8%, respectively. The method was applied on three beverage samples, energetic drink, and two different beer samples, and obtained recoveries were from 93.65 up to 104.96%. The throughoutput of the method was up to 90 analyses per hour.

AB  - The aim of this study was to determine and evaluate the amounts of major elements (Ca, Fe, K, Na and P), essential trace elements (Cu, Zn, Fe and Mn) and some other trace metals (Ag, Al, Co, Ni, Cr, Sr, Se, Bi, Rb) in eleven species of wild-grown common edible mushrooms from family Boletaceae (Boletus appendiculatus, Boletus edulis, Boletus regius, Boletus fechtneri, Boletus impolitus, Boletus purpureus, Boletus rhodoxanthus, Leccinum crocipodium, Leccinum pseudoscaber, Xerocomellus chrysenteron, Xerocomus badius) from Serbia. The measurements of major elements (Ca, Fe, K, Na and P) were carried out by inductively coupled plasma optical emission spectrometer (ICP-OES), while analytical measurements of the rest of studied elements were performed using an inductively coupled plasma mass spectrometer (ICP-MS), after microwave digestion. The results showed that the element concentrations were species-dependent. Potassium and phosphorous concentrations were found to be greater than those of the other mineral constituents in all tested species. Multivariate analysis included principal component analysis (PCA) and hierarchical cluster analyses (HCA). HCA grouped mushrooms in three statistically significant clusters, while PCA indicated connection between analyzed metals. Also, this paper highlights the importance of essential and nonessential elements of human health and their daily intake.

AB  - The influence of additives (alkyl polyglucoside, Glucopon 600 CS UP and alcohol ethoxylate C18E100) on the behavior of the water/toluene/Lutensol ON 50 (technical oxoalcohol, i-C10E5) microemulsion system as a function of temperature and composition has been investigated. The phase behavior of the microemulsions was determined by vertical sections through the Gibbs phase prism (fish-like phase diagrams). Alkyl polyglucoside shifts the one phase region to lower temperatures compared with water/toluene/Lutensol ON 50 mixtures. This is contrary to the expectation, considering the extreme hydrophilic nature of the sugar headgroup. The addition of hydrophilic alcohol ethoxylate (C18E100) to the water/toluene/Lutensol ON 50 system increases the solubilization capacity of the surfactant, even if the co-surfactant is used in small quantities, and shifts the one-phase region to higher temperature by a few degrees C.

AB  - Procedure for isolation of pyrrolizidine alkaloids (PAs) from Rindera umbellata Bunge plant species was optimised. Different extraction media (methanol, ethanol and sulphuric acid), concentration and volume of sulphuric acid, pH of PA solution for alkaline extraction, extraction time and techniques (maceration, ultrasonic and overhead rotary mixer assisted extraction) were investigated. The yields of six PAs (7-angeloyl heliotridane, 7-angeloyl heliotridine, lindelofine, 7-angeloyl rinderine, punctanecine and heliosupine) were monitored by GC-MS/FID. The best results for the isolation all of six PAs were obtained when the extraction was performed with 1M sulphuric acid (30mL per 1.00g of dried sample) by overhead rotary mixer during three days. Optimal pH value for alkaline extraction of PAs with CH2Cl2 was 9, and the extraction should be performed with four portions of 30mL of CH2Cl2. This procedure could be also useful for a plant sample preparation for GC and LC analyses of PAs.

AB  - Proteomic approach in combination with mass spectrometry demonstrates a great potential for identification of proteinaceous materials in works of art. In this study we used a linear trap quadrupole Orbitrap (LTQ-Orbitraph a state-of-the-art mass spectrometer for parts per million accuracy analyses of peptides behind tryptic hydrolysis. After the efficiency of the proteomic method was confirmed for reference and model samples, micro-samples from historical paintings were for the first time analysed using this technique. Superior performances of the liquid chromatography-mass spectrometry approach using a LTQ-Orbitrap mass spectrometer allowed identification of egg yolk peptides in two samples from nineteenth-century Orthodox icons, indicating egg tempera as the painting technique. Accurate precursor ion masses, in the range of 2 ppm, and retention times of tryptic peptides strengthen protein identification. Additionally, in all historical samples the presence of animal glues suggested that the ground layer was likely bound using bovine collagen. Comparing to results acquired using matrix-assisted laser desorption/ionization time-of-flight tandem mass spectrometry in our previous study, here we achieved higher ion scores and protein scores, better sequence coverage and more identified proteins. In fact, a combination of the two mass spectrometric techniques provided overlapping and complementary data, related to the detection of peptides with different physicochemical properties.

AB  - The examination of the aerial parts, roots, and seeds of the endemic plant Rindera umbellata is reported in this paper for the first time. Phytochemical investigation of R. umbellata led to the isolation and characterization of ten pyrrolizidine alkaloids and eleven fatty acids in the form of triglycerides. Pyrrolizidine alkaloids 1-9 were found in the aerial parts, 7 and 8 in the roots, and 6-10, together with eleven fatty acids, in the seeds of this plant species. The structures of compounds 1-10 were established based on spectroscopic studies (H-1- and C-13-NMR, 2D NMR, IR and CI-MS). After trans-esterification, methyl esters of the fatty acids were analyzed using GC-MS. The effect of lindelofine-N-oxide (7) on tubulin polymerization was determined.

AB  - Indirect determination of copper was based on determination of cyanide on working silver electrode. The system was equipped with two injection valves. One for injection of cyanide solution (reagent) and another one for the sample injection (copper solution). Carriers for cyanide and copper were 0.02 mol/L sodium-hydroxide and 0.01 mol/L hydrochloric acid, respectively. The copper determination in such system was severely interfered by the presence of cations forming stable cyano complexes [1]. The interferences were successfully removed off-line by applying appropriate chemical reaction. The most prominent interferants were nickel and zinc. By including the dumper in the FIA system, containing cotton wool soaked in an appropriate solution, nickel and zinc were successfully removed. Interferences from nickel were removed by soaking the wool in the alkaline solution of dimethylglyoxime (DMG) and the zinc was removed by soaking the wool in acidic solution of the p-NIAZOX (7-(4-nitrofenilazo)-8-hydroxyquinoline-5-sulfonic acid) [2]. The method was applied for determination of copper in real samples.

AB  - Aim of this work is to propose an analytical protocol for proteinaceous binder identification in paintings using tryptic peptide analysis and MALDI-TOF mass spectrometry strengthened with MALDI-TOF/TOF tandem mass spectrometry (LIFT method). Proteinaceous binders are enzymatically digested with trypsin. From each individual protein frequently occurring in binders, a specific set of peptides is releasing during enzymatic digestion giving a peptide mass fingerprint (PMF) of that particular protein. The most intensive peptide peaks in PMF were determined and annotated with their corresponding amino acid sequence by MALDI-TOF/TOF analysis and subsequent database search. Before analyzing historical painting samples, procedure was tested and optimized on several painting model samples for a reliable and efficient identification of proteinaceous materials. The method is avoiding sample manipulation as much as possible in order to reduce sample loss. Since the applied procedures led to protein identification of binding media in model samples, MALDI-TOF/TOF was for the first time applied for analysis of proteinaceous binders in old painting samples.

AB  - This study describes the effects of the substituents on electrochemical behavior and antioxidant activity of the six tetradentate Schiff bases, containing ethane-1,2-diamine or propane-1,2-diamine as the amine part and pentane-2,4-dione and/or 1-phenylbutane-1,3-dione as beta-diketone, and corresponding copper(II) complexes. Cyclic voltammograms of these compounds were recorded in dimethylsulfoxide and 0.1 M sodium perchlorate as supporting electrolyte with glassy carbon as working electrode at different scan rates. The voltammograms of Schiff bases alone showed only one irreversible peak. Voltammograms recorded for complexes showed the presence of quasi-reversible processes taking place at the metal center and reversible process at the ligand part. Both steric and inductive effects of substituents and structure of imine bridge of Schiff base ligands as well as complexes were discussed. These effects appear relevant for the antioxidant activity. Antioxidant activity of the investigated compounds expressed as Trolox equivalent antioxidant capacity is also discussed. The electrochemical behavior showed a high correlation with the antioxidant activity for investigated compounds.

AB  - A gas-diffusion flow injection method with amperometric detection for the indirect determination of copper on a silver electrode was developed. The flow through system was equipped with two injection valves and a gas-diffusion unit. In the first step, a signal of a cyanide solution was recorded. In the subsequent step, the signal of cyanide in the presence of copper was measured. Interferences (Cd(II), Co(II), Ag(I), Ni(II), Fe(III), Hg(II) and Zn(II)) were investigated and successfully removed. The calibration graph was linear in the range 1-90 mu mol dm(-3) of copper with a correlation coefficient of 0.993. The regression equation is I = (0.0455 +/- 0.0015)c + (0.4611 +/- 0.0671), where I is the relative signal decrease in mu A and c is concentration in mu mol dm(-3). Relative standard deviation for six consecutive injections of 30 mu mol dm(-3) copper(II) was 1.47 % and for 1 mu mol dm(-3) copper(II), it was 3.40 %. The detection limit, calculated as 3 s/m (where s is a standard deviation of nine measurement of a reagent blank and m is the slope of the calibration curve), was 0.32 mu mol dm(-3), which corresponds to 2.44 ng of copper(II) (the loop volume was 0.12 cm(3)). The method enables 60 analyses per hour and it was successfully applied for the determination of copper in drinking water samples.
AB  - Cilj ovog rada bio je razvoj gasno-difuzione protočno injekcione metode sa amperometrijskom detekcijom za indirektno određivanje bakra na srebrnoj elektrodi. Protočni sistem je opremljen sa dva injekciona ventila i gasno-difuzionom jedinicom. U prvom koraku snima se signal rastvora cijanida, a u drugom snima se signal pri istovremenom ubrizgavanju rastvora cijanida i rastvora bakra. Smetnje od Cd(II), Co(II), Ag(I), Ni(II), Fe(III), Hg(II) i Zn(II) su ispitane i uspešno uklonjene. Kalibraciona kriva je linearna u opsegu 1-90 μmol dm-3 bakra, koeficijent korelacije je 0,993, a jednačina prave I = (0,0455±0,0015)c + (0,4611±0,0671), gde je I razlika visine signala u μA, a c je koncentracija u μmol dm-3. Relativna standardna devijacija za šest uzastopnih ubrizgavanja rastvora bakra koncentracije 30 μmol dm-3 je 1,47 %, a za 1 μmol dm-3 rastvor Cu(II) je 3,40 %. Limit detekcije, izračunat kao 3s/m (gde je s standardna devijacija devet merenja slepe probe i m je nagib kalibracione prave), je 0,32 μmol dm-3, što odgovara 2,44 ng Cu(II) (zapremina petlje za uzorak je 0,12 cm3). Metoda omogućava 60 analiza po jednom satu i uspešno je primenjena za određivanje bakra u pijaćoj vodi.

Relative standard deviation for six consecutive injections of 30 mu mol dm(-3) copper(II) was 1.47 % and for 1 mu mol dm(-3) copper(II), it was 3.40 %. The detection limit, calculated as 3 s/m (where s is a standard deviation of nine measurement of a reagent blank and m is the slope of the calibration curve), was 0.32 mu mol dm(-3), which corresponds to 2.44 ng of copper(II) (the loop volume was 0.12 cm(3)). The method enables 60 analyses per hour and it was successfully applied for the determination of copper in drinking water samples., Cilj ovog rada bio je razvoj gasno-difuzione protočno injekcione metode sa amperometrijskom detekcijom za indirektno određivanje bakra na srebrnoj elektrodi. Protočni sistem je opremljen sa dva injekciona ventila i gasno-difuzionom jedinicom. U prvom koraku snima se signal rastvora cijanida, a u drugom snima se signal pri istovremenom ubrizgavanju rastvora cijanida i rastvora bakra. Smetnje od Cd(II), Co(II), Ag(I), Ni(II), Fe(III), Hg(II) i Zn(II) su ispitane i uspešno uklonjene. Kalibraciona kriva je linearna u opsegu 1-90 μmol dm-3 bakra, koeficijent korelacije je 0,993, a jednačina prave I = (0,0455±0,0015)c + (0,4611±0,0671), gde je I razlika visine signala u μA, a c je koncentracija u μmol dm-3. Relativna standardna devijacija za šest uzastopnih ubrizgavanja rastvora bakra koncentracije 30 μmol dm-3 je 1,47 %, a za 1 μmol dm-3 rastvor Cu(II) je 3,40 %. Limit detekcije, izračunat kao 3s/m (gde je s standardna devijacija devet merenja slepe probe i m je nagib kalibracione prave), je 0,32 μmol dm-3, što odgovara 2,44 ng Cu(II) (zapremina petlje za uzorak je 0,12 cm3). Metoda omogućava 60 analiza po jednom satu i uspešno je primenjena za određivanje bakra u pijaćoj vodi.",

AB  - Propranolol, a widely used beta-blocker, inhibits the hydrolysis reaction of enzyme cholinesterase. Measurements of the difference in rate of hydrolysis rate between uninhibited and inhibited reactions allow the development of a kinetic method for its determination. Both systems, enzyme-substrate-chromogen and enzyme-substrate-chromogen-inhibitor, were characterized through biochemical kinetic parameters (K-M, 0.326-0.330 mmol/L; V-max, 40.0-43.0 mu mol/Lmin). The inhibition type was recognized as competitive and the inhibition constant, Ki, was determined to be 22.60 mu mol/L. The detection and quantification limits were calculated as 0.004 and 0.0136 mu mol/L, respectively. Accuracy and precision of proposed methods were tested. The proposed method showed good sensitivity, selectivity, simplicity and rapidity, thus it is convenient for clinical applications.
AB  - Za propranolol, često propisivani neselektivni beta blokator, utvrđeno je da inhibira reakciju enzimske hidrolize butiriltioholin-jodida, koja je katalizovana serumskom holinesterazom. Merenjem razlike u brzini osnovne i inhibitorske reakcije hidrolize u prisustvu propranolola kao inhibitora, moguće je razviti kinetičku metodu za određivanje propranolola. Oba sistema, enzim-supstrat-hromogen kao i enzim-supstrat-hromogen-inhibitor, okarakterisani su biohemijskim kinetičkim parametrima (KM, 0,326-0,330 mmol/L; Vmax, 40-42,99 μmol/L min), inhibicija je definisana kao kompetitivna i određena je konstanta inhibicije 22,60 μmol/L. Da bi se u potpunosti iskoristile sve mogućnosti predložene metode u pogledu osetljivosti, tačnosti, preciznosti i selektivnosti, optimizovani su reakcioni uslovi. Konstruisana je kalibraciona prava, izračunata odgovarajuća jednačina i određeni granica detekcije i kvantifikacije i to 0,004 i 0,0136 μmol/L, redom. Tačnost i preciznost predložene metode su ispitane za tri koncentracije propranolola u oblasti kalibracione prave (0,082-21,120 μmol/L) u pet ponavljanja. Takođe, ispitan je uticaj većeg broja supstanci koje se mogu naći u uzorku na brzinu reakcije. Optimizovana metoda je primenjena za određivanje propranolola u farmaceutskim preparatima.

Predložena metoda ima dobru osetljivost, selektivnost, jednostavna je i brza, i nadasve lako dostupna, i na taj način primenljiva u velikom broju laboratorija.

AB  - Belgrade, capital city of Serbia, has over 1,600,000 inhabitants and over 400,000 vehicles trafficking every day on its streets. The investigation of soil pollution was performed by sequential extraction analysis to investigate the availability of potentially toxic metals (Zn, Cd, Pb, Co, Ni, Cu, Cr and Mn) under different oxidation and pH conditions. All investigated metals were mainly extracted from soils with neutral or acidic extractants. Serious pollution was observed along roads and streets with high traffic frequency, but Pb and Ni pollution was the highest since their concentrations exceed both soil Serbian standard and Canadian guidance values and is characteristic for all investigated sites. Cd, Cu, Cr and Zn concentrations are moderately high since they are between Canadian guideline and Serbian standard.

AB  - Natural monocrystalline pyrite and chalcopyrite were examined as new indicator electrodes for the potentiometric titration of weak acids in tert-butanol and iso-propanol. The electrodes investigated demonstrated a linear dynamic response for p-toluenesulfonic acid concentrations in the range from 0.1 to 0.001 M, with a Nernstian slope of 48 mV per decade for pyrite in tert-butanol. Sodium methylate, potassium hydroxide and tetrabutylammonium hydroxide (TBAH) proved to be suitable titrating agents. The response time was less than 12 s and the lifetime of the electrodes was higher than 1 year. The advantages of the electrodes are long-term stability, rapid response, reproducibility, easy preparation and low cost.

AB  - The indirect gas-diffusion flow injection method (FI) was modified, optimized and successfully applied to bromide determination in various samples such as active substances, drugs, organic substances and water samples. The method is based on the oxidation of bromide to bromine in acidic medium, which diffuses through PTFE membrane into the acceptor flow that carried bromine to the amperometric cell. The flow amperometric detection was carried out at the potential of +0.65 V (vs Ag/AgCl) when injected sample volume was 100 mu L. Results obtained by FIA were confirmed by cyclic voltarnmetry (CV). The linear calibration graph was obtained over the concentration range 0.1-10x10(-3) mol/L and 2.5-100x10(-6) mol/L bromide solutions. Relative standard deviation was 1.23% for 5x10(-6) mol/L bromide solution and 0. 11% for 0.25x10(-3)mol/L bromide solution (n=6, for both cases). The limit of detection was 5x10(-1) mol/L. The described method requires small quantities of samples and prior extraction of the analytes is not necessary. The method enables 60 analyses per hour.

AB  - A modification of the existing spectrophotometric kinetic method for the determination of pancuronium bromide (PCBr), based on pooled human serum cholinesterase (ChE, EC 3.1.1.8 acylcholine acylhydrolase) inhibition, was developed. Butyrylthiocholine iodide (concentration 1.667 mmol/L) was used as substrate and determination was performed at pH 7.6. Essential basic kinetic parameters were also determined: Michaelis-Menten's constant K-M=0.33 mmol/L, maximal reaction rate V-max=42.29 mu mol/ L min, inhibition constant K-I = 0.34 mu mol/L, and IC50=0.235 mu mol/L. Linear dependence between the reaction rate and the inhibitor concentration exists in PCBr concentration range 8.29-265.28 nmol/L, which corresponds to the real sample concentrations from 0.166 to 5.306 mu mol/L. The method detection limit was established to be 1.86 nmol/L and the quantification limit was 6.18 nmol/L. Precision of the method was tested for three pancuronium concentrations (16.58, 99.48, and 198.96 nmol/L). The relative standard deviation (RSD) was in the range 0.78-5.13%. Accuracy was examined by the standard addition method. The influence of substances usually present in serum and urine on the reaction rate was determined. The method developed was applied for PCBr determination in spiked serum and urine samples and in the urine taken during surgery. The method was proven to have good sensitivity, accuracy, and precision and can be considered suitable for clinical practice.

AB  - Pancuronium bromide (PCBr) inhibition effect on enzyme cholinesterase from pooled human serum (Che, EC 3.1.1.8 acylcholine acylhydrolase) was used for development of a spectrophotometric kinetic method for PCBr determination in human serum and urine. Optimal conditions for the basic and inhibitor reactions were established: pH=7.7 and substrate concentration c(benzoylcholine chloride)=1.33 mmol/L. Kinetic parameters were also determined: Michaelis-Menten's constant K-M=0.40 mmol/L, maximal reaction rate V-max=52.2 mu mol/L min, inhibition constant K-i=0,56 mu mol/L and IC50=1.31 mu mol/L. Linear dependence between the reaction rate and inhibitor concentration exists in PCBr concentration range 8.20-68.25 nmol/L, which corresponds to the real sample concentrations from 0.328 to 2.730 mu mol/L. The method detection and quantification limits were 2.01 nmol/L and 6.67 nmol/L, respectively. Precision of the method was tested for three pancuronium concentrations (10.70, 29.35 and 51.25 nmol/L). Relative standard deviation (RSD) was in the range 0.15-7.45%. Accuracy was examined by standard addition method. Influence of the substances usually present in serum and urine on the reaction rate was tested. The developed method was applied for PCBr content determination in serum model samples, urine model samples and in urine taken during surgery. The method has good sensitivity, accuracy, precision and it is suitable for clinical practice.

AB  - Eco-chemical characteristics of the soil from the Velika Morava River valley were examined by analysis of 27 samples of agricultural soil of fluvisol type. The main physico-chemical parameters (pH, carbonate, humus, total nitrogen, available potassium and phosphorus contents), and total and available contents of heavy metals (Pb, Zn, Cu and Cd) were determined. The aim of this research was to have an insight into the current eco-chemical state in the examined agricultural region, by detection of the main substrates of heavy metals, as well as by analysis of their possible origin. In all the examined samples, total Zn, Cu and Cd contents, and in most of the examined samples, total contents of Pb, obtained by sequential extraction, were below maximum allowed concentrations (MAC) for agricultural soils. The increased content of total Pb (104.28-161.03 mg/kg) in some of the examined samples was probably caused by anthropogenic activity. Results of the sequential extraction, as, well as the extraction with diethylene triamine pentaacetic acid (DTPA), used for extraction of available metals, indicated the anthropogenic sources of Pb, Cu and Cd, whereas Zn was most often of geochemical, native origin. The obtained results were subject to correlation and factor analysis. Both methods confirmed the correlation between Zn and Cd, leading to the conclusion that a part of Zn was also of, anthropogenic origin. Factor analysis brought together total contents of Zn and Cd, and pH-value of the soil, and indicated the possibility of its easy mobilisation at slight changes in soil acidity.

AB  - The kinetic spectrophotometric method for Au(III) determination was developed and validated. It was based on the catalytic effect of gold on the oxidation of methylene blue B (3,7di-(dimethyl amino)-10-dehydro-phenotiazin chloride) by ammonium peroxo-disulfate in citric buffer solution. There was the linearity of the calibration curve in the concentration range from 0.09 to 2.90 mu g ml(-1) Au(III). The relative standard deviation was 2.50% and correlation coefficient of 0.9999. The limit of detection was determined as signal to noise ratio (3: 1) and it was 5.5 ng ml(-1). The limit of quantification, based on signal to noise ratio 10: 1 was 19.25 ng ml(-1). The selectivity was tested on the basis of influence of known amounts of different ions in the reaction mixture, upon the reaction rate. Kinetic and thermodynamic parameters were reported for both catalytic and non-catalytic reactions. The method was verified by Au(III) determination in anti-rheumatic drug "Thuredon" and in human urine samples, using ICP-AES as the comparative method. As the method is accurate, reliable, quick and simple it could be useful for clinical and toxicological practice. (c) 2004 Elsevier B.V. All rights reserved.

AB  - A selective and sensitive procedure for the fast and indirect determination of chloride by the gas-diffusion FIA method has been optimized and applied for the determination of chloride in water samples which contained different amounts of the analyte. The examined samples were: seawater, tap water and very pure water from the water-steam system of the power plant "Nikola Tesla B" in Obrenovac. Application of an amperometric detector (model LC-17A; BAS, West Lafayette, USA) enables the detection limit to be decreased down to 0.05 mu mol/dm(3) of chloride, which col responds to 35.5 pg, and adjustment of the acceptor flow rate and direction inside the gas-diffusion unit. In this way the optimized FIA system has excellent repeatability. For 5 mu mol/dm(3) it was found to be 1.11% (n = 5). The throughput of this method is 60 samples per hour.
AB  - Selektivan i osetljiv postupak za brzo, indirektno određivanje hlorida gasno-difuzionom metodom otpimizovan je i primenjen za određivanje hlorida u uzorcima voda sa vrlo različitim sadržajem ove vrste: morskoj, vodi za piće i vrlo čistim vodama u sistemu voda-para TE "Nikola Tesna B" u Obrenovcu. Upotreba amperometrijskog detektora tipa LC-17A omogućava snižavanje granice detekcije na 0.05 μmol/dm3 hlorida (što za uzorak zapremine 0.2 cm3 iznosi 35.5 pg) i podešavanje brzine i smera toka u gasno-difuzionoj jedinici. Ovako optimizovan protočni sistem ima odličnu reproduktivnost. Za hloridni standard koncentracije 5 μmol/dm3 relativna standardna devijacija iznosi 1.11 % (n = 5).

The throughput of this method is 60 samples per hour., Selektivan i osetljiv postupak za brzo, indirektno određivanje hlorida gasno-difuzionom metodom otpimizovan je i primenjen za određivanje hlorida u uzorcima voda sa vrlo različitim sadržajem ove vrste: morskoj, vodi za piće i vrlo čistim vodama u sistemu voda-para TE "Nikola Tesna B" u Obrenovcu. Upotreba amperometrijskog detektora tipa LC-17A omogućava snižavanje granice detekcije na 0.05 μmol/dm3 hlorida (što za uzorak zapremine 0.2 cm3 iznosi 35.5 pg) i podešavanje brzine i smera toka u gasno-difuzionoj jedinici. Ovako optimizovan protočni sistem ima odličnu reproduktivnost. Za hloridni standard koncentracije 5 μmol/dm3 relativna standardna devijacija iznosi 1.11 % (n = 5).",
