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...

Here we present an advanced platform for the analysis of specialized pro-resolving mediators (SPM), including a set of pro-inflammatory lipids and respective biochemical pathway markers. The platform is characterized by a largely simplified sample preparation protocol, employing methanol protein-precipitation instead of solid phase extraction....

An HPLC method was developed for estimation of dermal exposure of greenhouse workers to the pesticide bupirimate. Chromatography was performed on a cyano-modified silica column with methanol-water (6:4 by volume) containing 5 g/L ammonium sulfate as eluent. UV detection at 310 nm was used for quantitation. Dermal exposure was assessed by letting...
