F2-isoprostanes are a family of prostaglandin F2-like compounds that are formed by free-radical-catalyzed peroxidation of arachidonic acid. Several F2-isoprostanes, but in particular 8-epi PGF(2alpha), are widely used as oxidative stress biomarkers. An analytical method based on liquid chromatography with negative

A qualitative determination of 20 underivatized proteinic amino acids by LC-MS is reported. The need for chromatographic separation before mass spectrometry determination is demonstrated based on the study of several amino acid pairs which have some similar characteristics. Two suitable

A sensitive, specific and precise HPLC-UV assay was developed to quantitate cocaine (COC) and its metabolites benzoylecgonine (BE), norcocaine (NC) and cocaethylene (CE) in rat plasma. After adding 50 microl of the internal standard solution (bupivacaine, 8 microg/ml) and 500

A reversed-phase high-performance liquid chromatographic method with electrochemical detection has been developed for the determination of buspirone from human plasma. The separation was carried out by using a Supelcosil ABZ+ plus C18 reversed-phase column and 0.05 M potassium dihydrogenphosphate (pH
Journal of chromatography. A, 957(2), 173-185 (2002-07-13)
The single run analysis of 23 small peptides (principally glycyl and lysyl dipeptides) is performed by ion-pair reversed-phase liquid chromatography coupled with evaporative light scattering detection or electrospray (tandem) mass spectrometry. Several perfluorinated carboxylic acid homologues are evaluated with an
