Multi-Residue Screening and Confirmatory Analysis of Anabolic Steroids in Urine by Gas Chromatography Coupled with Tandem Mass Spectrometry

peer reviewedThe diversity of substances used illegally as growth promoters in meat production requires the development of multi-analyte methods of analysis involving a sample pretreatment step that is as rapid and as easy as possible, followed by a specific and sensitive determination of several residues within the same run. A general strategy for the screening and confirmatory analysis of fifteen artificial anabolic compounds in urine samples is described. It is based on solid-phase extraction on C18 Empore discs and amino-bonded columns followed, after derivatization (trimethylsilyl or methyloxime-trimethylsilyl derivatives), by gas chromatography coupled with collisionally activated dissociation tandem mass spectrometry

Structural analysis of two pyoverdins by electrospray and FAB mass spectrometry

peer reviewedPyoverdins are chromopeptides produced by the so-called fluorescent group of the bacterial genus Pseudomonas. Species or even strain specific they differ in the composition of their peptide chains. For classification purposes it is of importance to get fast information regarding the nature of the latter. For two new representatives from hydrolysis results and especially from an analysis of the data obtained from electrospray ionization (ESI) and fast atom bombardement (fAn) mass spectrometry measurements the amino acid sequences can be suggested as Asp-BuOHOrn-Dab-aThr-Gly-Ser-Ser-OHAsp-aThr (Pseudomonas putida BTP16) and Ser-SerFoOHOrn-Ser-Ser-Ser-FoOHOrn-Lys-Lys (Pseudomolnas fluorescens BTP7)
