New method of derivatization and headspace solid-phase microextraction for gas chromatographic-mass spectrometric

Abstract:
A simple method for hair analysis of methamphetamine (MAMP) and amphetamine (AMP) by gas chromatography-mass spectrometry (GC-MS) was developed using simultaneous headspace solid-phase microextraction (HS-SPME) with derivatization. After alkaline-digestion of hair, the analytes derivatized with heptafluoro-n-butyryl chloride were adsorbed on a polydimethylsiloxane-coated fiber by HS-SPME and analyzed by GC-MS. Their mass spectra were, respectively, observable at 1 ng per sample. The standard curves in the range of 0.1-100 ng were linear. The intra-day coefficients of variation at each 0.5 ng were 12.5% for AMP and 3.8% for MAMP. The applicability of this method was demonstrated in some case studies.
