title: Quantitative determination of nitroglycerol in human plasma by gas chromatography negative ion mass spectrometry using 15N labelled nitroglycerol as internal standard.
abstract: Negative ionization resulted in the simplification of a previously published method. The new method permits the determination of 0.25 nmol l-1 nitroglycerol in plasma with a coefficient of variation of 9.1%.
