European analytical column number 48
(Springer Nature, 2020)
The European Analytical Column is the voice of the Division of Analytical Chemistry (DAC) as a professional network of chemical societies and their members working in all fields of analytical sciences within the European ...
Determination of ascorbic acid in pharmaceutical dosage forms and urine by means of an oscillatory reaction system using the pulse perturbation technique
(Springer Heidelberg, Heidelberg, 2007)
A simple and reliable method for the determination of ascorbic acid (AA) is proposed and validated. It is based on potentiometric monitoring of the concentration perturbations of an oscillatory reaction system in a stable ...
European analytical column number 46

Characterization of bonded stationary phase performance as a function of qualitative and quantitative chromatographic factors in chaotropic chromatography with risperidone and its impurities as model substances
(Springer Heidelberg, Heidelberg, 2018)
Numerous stationary phases have been developed with the aim to provide desired performances during chromatographic analysis of the basic solutes in their protonated form. In this work, the procedure for the characterization ...
Quantitative structure -retention relationship modeling of selected antipsychotics and their impurities in green liquid chromatography using cyclodextrin mobile phases
(Springer Heidelberg, Heidelberg, 2018)
Applying green chromatography methods is currently one of the challenges in liquid chromatography. Among different strategies, using cyclodextrin (CD) mobile phase modifiers was applied in this paper. CDs can form inclusion ...
Microquantitative determination of hesperidin by pulse perturbation of the oscillatory reaction system
(Springer Heidelberg, Heidelberg, 2005)
A simple and reliable kinetic method for the determination of hesperidin (Hesp) is developed. It is based on potentiometric monitoring of the concentration perturbations of the matrix reaction system which is in a stable ...
The evaluation of short- and long-term stability studies for brimonidine in aqueous humor by DPV/BDDE method—possible application for direct assay in native samples
(Springer Verlag, 2019)
A novel voltammetric method was developed for brimonidine (BRIM) determination in deproteinized aqueous humor, simplifying preparation of biological samples for analysis for stability studies. The differential pulse ...
Quantitative structure-property relationship modeling of polar analytes lacking UV chromophores to charged aerosol detector response
(Springer Heidelberg, Heidelberg, 2019)
In this study, a quantitative structure-property relationship model was built in order to link molecular descriptors and chromatographic parameters as inputs towards CAD responsiveness. Aminoglycoside antibiotics, sugars, ...
Euroanalysis XVI-challenges in modern analytical chemistry
