Disopyramide determination by gas chromatography, liquid chromatography, and gas chromatography--mass spectrometry.
Disopyramide is determined in serum by gas chromatography with a nitrogen-selective detector, by liquid chromatography, and by gas chromatography--mass spectrometry. Comparable results are obtained with the three techniques, with a within-run and between-run precision of 5 to 10% (coefficient of variation). Least-squares analysis of data on patients' sera, analyzed first by gas chromatography (...
متن کاملGas chromatography-mass spectrometry determination of polybrominated
Gas chromatography coupled to mass spectrometry in negative chemical ionization (NCI) 11 mode has been applied to the quantification and reliable identification of polybrominated 12 diphenyl ethers (PBDEs) in animal and vegetable samples from aquaculture activities. 13 Matrices analyzed included fish fillet, fish feed, fish oil and linseed oil, which their fat content 14 ranged from 5 to 100%. ...
متن کاملGas Chromatography Mass Spectrometry Coupling Techniques
Relative to other metabolomics analysis techniques, gas chromatography mass spectrometry (GC/MS) is one of the earliest applied analysis techniques in metabolomics. The first paper on metabolomics (metabolic profiling) is derived from the application of GC/MS analysis in urine and tissue extracts (Dalgliesh et al. 1966). With the arrival of omics era and the proposing of metabolomics concept, p...
متن کاملDetermination of coumarin in fragrance products by capillary gas chromatography with electron capture detection.
A gas chromatographic (GC) method is described for the determination of coumarin in fragrance products. Coumarin was tentatively identified by retention time and confirmed by GC/mass spectrometry. The amount of coumarin was determined by external standard. The method was validated by conducting recovery studies from fortified fragrance products at several concentrations. Recoveries of coumarin ...
