AbstractProcedures are developed for the multielement analysis of high-purity cerium oxide for the manufacture of phosphors and optical materials using inductively coupled plasma–mass spectrometry (ICP–MS) and inductively coupled plasma–optical emission spectrometry (ICP–OES). The “robust” settings of the mass spectrometer are given suitable to det...

AbstractThe ChemSpider and PubChem chemical databases used in non-target mass spectrometry analysis in order to outline the candidates for identification are described. Relevant compounds are searched by molecule-containing ion masses (only ChemSpider) or by molecular formulas before determined (both databases). The compounds that are highly cited ...

AbstractLiquid phase microextraction is a state-of-the-art micro-analytical work with numerous advantages documented in the scientific literature. One of the most intriguing subclasses is the CO2-effervescence assisted dispersive liquid−liquid microextraction method. Working theory was based on an acid-based reaction involving a proton donor and a ...

AbstractThe electrochemical and analytical characteristics of enantioselective sensors based on glassy carbon electrodes modified by chelate complexes (bis(L-phenylalaninate) copper(II), glycinato-L-phenylalaninate copper(II), tris(L-phenylalaninate) cobalt(II), bis(L-phenylalaninate) zinc) are studied. It is found that the most promising sensor fo...

AbstractDNA sequencing is an essential task of modern molecular genetic research. Its fundamental parameter is the accuracy of decoding. In this work, we determined the maximum lengths of DNA fragments, obtained by the Sanger method and sequenced with an accuracy of 99%, in a polymer based on linear poly(N,N-dimethylacrylamide) PDMA-6 for capillari...

AbstractWe recorded and interpreted DART mass spectra of Hoveyda–Grubbs catalysts with N→Ru and S→Ru coordination bonds. The set of ions formed under DART ionization conditions is similar to those obtained using matrix-assisted laser desorption/ionization mass spectrometry. The optimal conditions (ionization gas, gas flow temperature) for recording...

AbstractThe work aims at developing fluorimetric methods used for bioassay to expand the range of the determined low-molecular-weight organic analytes and cut down sample preparation operations using available fluorophores, reagents, and identical fluorimetric systems for qualitative and quantitative analysis. We proposed using the reaction of carb...

AbstractFour simple, precise and sensitive visible spectrophotometric methods were developed for the determination of solifenacin succinate in pure and pharmaceutical dosage forms. The proposed methods were based on the estimation of unreacted N-bromosuccinimide (NBS) with four dyes, namely, amaranth, safranin, aniline blue and rhodamine B, by the ...

AbstractWe developed an enantioselective voltammetric sensor based on a carbon-paste electrode modified by enantiomorphic crystals of bromotriphenylmethane for the recognition and determination of tryptophan enantiomers. Enantiomorphic crystals of bromotriphenylmethane were obtained under the condition of Viedma ripening. The electrochemical and an...

AbstractThe drift time and ion mobility of imidazole are determined and a procedure for the mathematical processing of spectra is developed. The specific features of changes in the ion mobility spectrum during measurements at a particular time are studied. The structures of the generated ions are proposed based on the interpretation of spectral sig...
