Qualitative and quantitative analysis of methamphetamine and amphetamine in biologic materials was carried out by gas chromatography/ mass spectrometry. A deuterium-labeled methamphetamine was employed as an internal standard with a detection limit of 50 pg and absolute stability and reproducibility

โฆ Synopsis
Pentodeuterated 4-hydroxymethamphetamine(HMAMP-d5),l-(4-hydroxyphenyl)-2-(methyl-d3-amino)-propane-l,2-d2 of high quality was prepared and proved to be a most useful internal standard for quantitative analyses of 4-hydroxymethamphetamine (HMAMP), a main metabolite of methamphetamine(MAMP). Highly reliable results were obtained by gas chromatography/mass spectrometry. Simultaneously we determined also MAMP, amphetamine(AMP), 4-hydroxyamphetamine(HAMP), and HMAMP in body fluids, using two internal standards, HMAMP-d5 for HMAMP and HAMP and pentodeuterated methamphetamine, 1-phenyl-2-(methyl-d3-amino)-propane-l,2-d2, for MAMP and AMP.

## Abstract A new, specific and sensitive GCโMS method with electron impact ionization technique was developed for quantitative analysis of ezetimibe (EZE) in human plasma. Prior to GC analysis, EZE was derivatized with __N__โmethylโ__N__โtrimethylsilylโtrifluoroacetamide (MSTFA), which is a trimet
