The conversion of oestrogens into mixed derivatives comprising a phenolic silyl ether and one or more alcoholic perfluoroactyl ester(s) is described. They are easily formed in quantitative yield and have excellent gas chromate graphic and mass spectrometric properties, making them suitable for analy

The method involves a single extraction of the drug and the internal standard, etidocaine, from alkalinized plasma with n-hexane. The gas chromatograph is equipped with a glass column (2.0 m x 2 mm) packed with 3% W/W SP2250 on Chromosorb W, (80/100 mesh) and a nitrogen sensitive detector. The metho
## Abstract A simple, sensitive and specific liquid chromatography‐tandem mass spectrometry method for the quantification of bromopride I in human plasma is presented. Sample preparation consisted of the addition of procainamide II as the internal standard, liquid‐liquid extraction in alkaline cond
Microbial denitrification is a fundamental reaction sequence within the global cycle of nitrogen that returns fixed nitrogen to its elementary state. In denitrification studies there is a need for an efficient gas analysis system that should meet the following requirements: (i) NO, NzO, N2 and O2 as
A simple, selective and specific liquid chromatography method was used to simultaneously determine the cis-cis, cis-trans and trans-trans isomers of mivacurium in human and dog plasma. Solid phase extraction was used to separate interfering endogenous products from the compounds of interest. Fluorom
## Abstract A highly sensitive, rapid assay method has been developed and validated for the estimation of omeprazole (OPZ) in human plasma with liquid chromatography coupled to tandem mass spectrometry with electrospray ionization in the positive‐ion mode. The assay procedure involves alkalinizatio
