We have developed an analytical method, consisting of ion-pair liquid chromatography coupled to electrospray ionization mass spectrometry (IP-LC-ESI-MS), for the simultaneous quantitative analysis of several key classes of polar metabolites, like nucleotides, coenzyme A esters, sugar nucleotides, and sugar bisphosphates. The use of the ion-pair...

The potential of microcolumn liquid chromatography (╬╝LC) and capillary electrophoresis (CE) with on-line, flame photometric detection (FPD)in the P-selective mode has been studied for determination of polar P-containing pesticides, glyphosate and its main metabolite, aminomethylphosphonic acid (AMPA), ethephon, fosetyl-aluminium and acephate....

A straightforward and reliable method was developed for the determination of chlormequat in pears by liquid chromatography/mass spectrometry (LC/MS). Water and methanol were compared as extraction solvents. Because no significant differences in extraction efficiency or repeatability were found, water was chosen as the extraction solvent. The...
