HPLC-DAD for analysis of different classes of drugs in plasma
Journal of Clinical Forensic Medicine, 2005A solid-phase extraction technique and HPLC-DAD method for drug screening in plasma were developed. This analytical method extracts and tests a number of drugs of different classes. The method includes; an acidic and basic Solid Phase Extraction (SPE) of plasma with C18 cartridges, a gradient elution of a modified cyano column with acidic buffer ...

Identification of Dyes on Single Textile Fibers by HPLC-DAD-MS
Analytical Chemistry, 2013An HPLC-DAD-MS method is described to analyze textile dyes in different dye classes (reactive, basic, acid, direct, disperse). The described method is sensitive enough to analyze single fibers with a length of a few millimeters or less, which makes it suitable for forensic analyses.

Conformational study on telaprevir by HPLC–DAD–MS and theoretical calculation
Biomedical Chromatography, 2019AbstractTelaprevir is a potent, selective, peptidomimetic inhibitor of the hepatitis C virus (HCV) NS3‐4A serine protease. it is used for the treatment of HCV infection in combination with peginterferon alfa and ribavirin. In the present work, the E–Z isomerization process of telaprevir in solution was revealed by online HPLC–DAD (diode array detector)–

HPLC–DAD protein kinase inhibitor analysis in human serum
Journal of Chromatography B, 2012We here describe an HPLC-DAD method to analyse different protein kinase inhibitors. Potential applications of this method are pharmacokinetic studies and therapeutic drug monitoring. Optimised chromatography conditions resulted in a very good separation of seven inhibitors (vatalanib, bosutinib, canertinib, tandutinib, pazopanib, dasatinib - internal ...
