An HPLC assay with tandem mass spectrometric detection in the positive-ion Turbo-Ion-Spray((TM)) (TISP) mode for the fast and sensitive determination of perifosine ((I), D-21266) in human plasma was developed, utilising the structural analogue, miltefosine ((II), D-18506), as internal standard. Automated solid-phase extraction of diluted plasma...

The drug salbutamol (SBL) is a β-agonist that may be used illegally as an animal growth promoter. SBL is also a good example of a drug which is excreted in the form of glucuronides and sulfates. Such metabolites cause complexities in analysing for the presence of drug residues. In the majority of cases a process of deconjugation and sample clean...

A technique for the detection of biotransformation products of xenobiotics in crude urine extracts by field desorption mass spectrometric profile analysis is described. The method comprises determination of peak profiles of a series of blank and test samples using low resolution field desorption mass spectrometry, comparison of averaged peak...
