Identification of protein binders in artworks by MALDI-TOF/TOF tandem mass spectrometry
(Elsevier Science Bv, Amsterdam, 2013)
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 ...
Interpretative optimization and artificial neural network modeling of the gas chromatographic separation of polycyclic aromatic hydrocarbons
(Elsevier Science Bv, Amsterdam, 2008)
An interpretative strategy (factorial design experimentation + total resolution analysis + chromatogram simulation) was employed to optimize the separation of 16 polycyclic aromatic hydrocarbons (PAHs) (naphthalene, ...
Dinuclear copper(II) octaazamacrocyclic complex in a PVC coated GCE and graphite as a voltammetric sensor for determination of gallic acid and antioxidant capacity of wine samples
(Elsevier Science Bv, Amsterdam, 2015)
A novel efficient differential pulse voltammetric (DPV) method for determination gallic acid (GA) was developed by using an electrochemical sensor based on [Cu(2)tpmc](ClO4)(4) immobilized in PVC matrix and coated on ...
Selectivity in analytical chemistry: Two interpretations for univariate methods
(Elsevier Science Bv, Amsterdam, 2015)
Selectivity is extremely important in analytical chemistry but its definition is elusive despite continued efforts by professional organizations and individual scientists. This paper shows that the existing selectivity ...
Comparison of the single channel and multichannel (multivariate) concepts of selectivity in analytical chemistry
(Elsevier Science Bv, Amsterdam, 2015)
Different measures of selectivity are in use for single channel and multichannel linear analytical measurements, respectively. It is important to understand that these two measures express related but still distinctly ...
Effect of cobalt doping level of ferrites in enhancing sensitivity of analytical performances of carbon paste electrode for simultaneous determination of catechol and hydroquinone
(Elsevier Science Bv, Amsterdam, 2016)
This work presents the simultaneous determination of catechol (CC) and hydroquinone (HQ), employing a modified carbon paste electrode (CPE) with ferrite nanomaterial. Ferrite nanomaterial was doped with different amount ...
Comparative study of different approaches for multivariate image analysis in HPTLC fingerprinting of natural products such as plant resin
(Elsevier Science Bv, Amsterdam, 2017)
Considering the introduction of phytochemical fingerprint analysis, as a method of screening the complex natural products for the presence of most bioactive compounds, use of chemometric classification methods, application ...

Kinetic method for the determination of traces of thyroxine by its catalytic effect on the Mn(III) metaphosphate-As (III) reaction
(Elsevier Science Bv, Amsterdam, 2008)
A new, highly sensitive and simple kinetic method for the determination of thyroxine was proposed. The method was based on the catalytic effect of thyroxine on the oxidation of As(III) by Mn(III) metaphosphate. The kinetics ...
Determination of metal content in some herbal drugs - Empirical and chemometric approach
(Elsevier Science Bv, Amsterdam, 2005)
The concentrations of Cu, Zn, Mn, Fe, K, Ca, Mg, Al, Ba and B in 26 herbal drugs of special importance in phytopharmacywere studied. Flame atomic absorption and emission spectrometry (FAAS, FAES), as well as inductively ...
