Simultaneous Determination of the Endogenous Free α-Lipoic Acid and Dihydrolipoic Acid in Human Plasma and Erythrocytes by RP-HPLC with Electrochemical Detection

25-Mar-2011 | Muhammad Imran Khan, Zafar Iqbal, Lateef Ahmad, Yasar Shah, Shabnam Nazir, Abbas Khan, Fazli Nasir, Chromatographia, 2011

A highly sensitive, precise, and accurate reversed-phase high-performance liquid-chromatography/electrochemical detection method for simultaneous determination of the endogenous free α-lipoic acid and dihydrolipoic acid in biological matrices was developed and validated. The two analytes were ...

General Strategy for Performing Temperature Programming in High Performance Liquid Chromatography: Prediction of Linear Temperature Gradients

16-Feb-2011 | Steffen Wiese; Thorsten Teutenberg; Torsten C. Schmidt, Analytical Chemistry, 2011

This paper describes how an empirical retention model is transferred from temperature-programmed gas chromatography (GC) to high temperature liquid chromatography (HT-HPLC). In order to evaluate the retention prediction, a temperature range from 50 to 180 °C was investigated using two test ...

Computer-assisted modelling and optimisation of reversed-phase high-temperature liquid chromatographic (RP-HTLC) separations

21-Aug-2010 | J. García-Lavandeira, P. Oliveri, J. A. Martínez-Pontevedra, M. H. Bollaín, M. Forina, R. Cela, Analytical and Bioanalytical Chemistry, 2010

The use of high temperatures (above 100 °C) in reversed-phase liquid chromatography (RP-HTLC) has opened up novel and enhanced applications for this essential separation technique. Although the favourable effects of temperature on LC have been extensively studied both theoretically and ...
