This study highlights the capability to conduct a post column derivatisation (PCD) process with a narrow bore, low volume column. A reaction flow (RF) HPLC column (30 mm × 2.1 mm internal diameter (i.d.), 3 μm particle ...

Introduction: An efficient characterisation of metabolites is a crucial task in many aspects of basic research, such as the de-replication of crude extracts in natural products chemistry or the tentative identification of ...

An established ferric reducing antioxidant power (FRAP) assay was optimised by preparation of the derivatisation reagent in 300 mM formate instead of 300 mM acetate conditions, resulting in increased sensitivity signal to ...

This study is based upon a recently established method for quantification of the antioxidant capacity of natural samples via a HPLC separation and a hyphenated selective detection (post-column derivatization with cupric ...

Although the action of Gonyautoxins (GTXs) and Saxitoxin (STX) mechanisms is well known at the molecular level, there are still many unresolved questions associated with the intoxication syndrome in mammals. For example, ...

El Glifosato es el herbicida más utilizado y comercializado a nivel mundial usado principalmente para el control de malezas. El uso excesivo y su impacto en el medio ambiente, ha promovido el análisis químico del Glifosato ...
