Journal of analytical toxicology, 14(1), 12-17 (1990-01-01)
Pentafluoropropionic anhydride (PFPA) and heptafluorobutyric anhydride (HFBA) derivatives of morphine and codeine demonstrated poor spectra due to low abundances of secondary and tertiary ions. Trifluoroacetamide (MBTFA) has been a widely used derivative; however, the internal standard, nalorphine, displayed very poor

We developed a fast and sensitive method for identification and quantification of plasma concentrations of amphetamine using gas chromatography with mass spectrometry detection (GC-MS). Amphetamine-d8 served as internal standard. The method involves a single extraction procedure and an easy treatment
