(author), TNO Kwaliteit van Leven TNO Voeding (author)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...article 2006

(author)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....article 2014

Medisch Biologisch Laboratorium TNO (author), Jongen, M.J.M. (author), Engel, R. (author), Leenheers, L.H. (author)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...article 1992
