A sensitive and specific gas chromatography/mass spectrometry (GC/MS) method has been developed for the simultaneous analysis of methampthetamine and its metabolites (amphetamine, p-hydroxymethamphetamine, and p-hydroxyamphetamine) in monkey urine. The method has been applied to the analysis of urine samples from

A highly-sensitive analytical method for the detection of p-hydroxymethamphetamine (pOHMA) in urine is presented. The proposed method combines liquid-liquid extraction with acetonitrile and solid-phase extraction by thin-layer chromatography (TLC) with oxidation using potassium hexacyanoferrate(III) and sodium hydroxide to detect the

A simple, rapid and highly sensitive high-performance liquid chromatographic method for the determination of methamphetamine and its metabolites in human urine was developed. Without tedious pretreatment procedures, aliquots of methamphetamine spiked or abusers' urine samples were simply acidified, dried under
