A rapid method of qualitative identification of barbituric acids, which does not require prior isohtioil of the barbiturate from the pharmaceutical dosage forni, was developed utilizing mass spectrometry. This is achieved by the introduction o f a portion of the powdered preparation directly into th
In gas chromatography/mass spectrometry (GC/MS) with magnetic instruments and quadrupoles, skewed ('tilted') spectra are obtained owing to the changes in analyte concentrations in the source of the mass spectrometer during the measurements of one scan. Skewing depends on the ratio of cycle time to G
