The performance of electrospray ionization and atmospheric pressure chemical ionisation (APCI) for the analysis of carotenoids was investigated. On our instrument, APCI produced spectra which were readily interpreted, and the positive-ion mode proved applicable to all of the compounds. The separatio
A liquid chromatographic atmospheric pressure chemical ionization tandem mass spectrometric method is described for the determination of 21-hydroxydeflazacort in human plasma using dexamethasone 21-acetate as an internal standard. The procedure requires a single diethyl ether extraction. After evapo
The determination of S-carboxymethyl-(R)-cysteine (SCMC) in human plasma during extended bioequivalence studies demands a rapid, accurate and selective assay technique. A liquid chromatographic/mass spectrometric method was developed which involves rough protein precipitation followed by high-perfor
