Chiral ligand-exchange chromatography for diastereo-enantio separation of exametazime
(Pergamon-Elsevier Science Ltd, Oxford, 2003)
The diastereo-enantio separation of isomeric mixtures of exametazime (HM-PAO) by liquid chromatography is described using an achiral sorbent (RP-18). A chiral eluent with the initial complex of Cu(II) and the optically ...
Quality by Design approach in the development of hydrophilic interaction liquid chromatographic method for the analysis of iohexol and its impurities
(Elsevier Science BV, Amsterdam, 2015)
This study presents the development of hydrophilic interaction liquid chromatographic method for the analysis of iohexol, its endo-isomer and three impurities following Quality by Design (QbD) approach. The main objective ...
Use of ANN modelling in structure-retention relationships of diuretics in RP-HPLC
(Pergamon-Elsevier Science Ltd, Oxford, 1999)
Structure-retention relationship study, conducted by RP-HPLC, was used to investigate physical chemical parameters related to the RP retention times of amiloride, hydrochlorothiazide and methyldopa in order to predict the ...
Isocratic RP-HPLC method for rutin determination in solid oral dosage forms
(Pergamon-Elsevier Science Ltd, Oxford, 2007)
A rapid and sensitive assay for quantitative determination of rutin in oral dosage forms based on isocratic reversed phase high performance liquid chromatography (RP-HPLC) was developed and validated. Using a C-18 reverse-phase ...
Corona Charged Aerosol Detector in studying retention and β-cyclodextrin complex stability using RP-HPLC
(Elsevier B.V., 2021)
Binding between cyclodextrin (CD) cavity and guest molecule in Reversed Phase High-Performance Liquid Chromatography (RP-HPLC) is dynamic process. In general, increasing CD concentration is inducing inclusion complex ...
Quantitative structure-retention relationship of selected imidazoline derivatives on alpha(1)-acid glycoprotein column
(Elsevier Science BV, Amsterdam, 2016)
The retention behaviour of 22 selected imidazoline drugs and derivatives was investigated on alpha(1)-acid glycoprotein (AGP) column using Sorensen phosphate buffer (pH 7.0) and 2-propanol as organic modifier. Quantitative ...
Spectrophotometric study of diclofenac-Fe(III) complex
(Pergamon-Elsevier Science Ltd, Oxford, 1997)
A multifactor optimisation technique is successfully applied to develop a new spectrophotometric method in which diclofenac sodium is analysed and determined as it's Fe(III) complex. The effect of simultaneously varying ...
Trace elements analysis of Echinacea purpurea - herbal medicinal
(Elsevier Science BV, Amsterdam, 2003)
Elemental composition of Echinacea purpurea (Asteracae), grown in Serbia under strongly controlled conditions, has been studied. To distinguish elemental patterns of different parts of the plant, the content of Zn, Fe, Cu, ...
Photochemical degradation of solid-state nisoldipine monitored by HPLC
(Pergamon-Elsevier Science Ltd, Oxford, 2003)
The photochemical degradation of solid-state nisoldipine, 1,4-dihydropyridine calcium antagonist, was investigated under daylight and UV light conditions. Degradation products were identified by using the retention times ...
Development and validation of reversed phase high performance liquid chromatographic method for determination of moxonidine in the presence of its impurities
(Elsevier Science BV, Amsterdam, 2012)
A simple, rapid, isocratic reversed-phase high-performance liquid chromatographic method was developed and validated for the analysis of moxonidine and its impurities in tablet formulations. The chromatographic separation ...
