4 Principles

Extraction of L-methamphetamine and D-methamphetamine (see Appendix A for compound information) in suspected drug samples. using liquid Gas chromatography-mass spectrometry detection, with retention time, mass spectrometry characteristic ion pair and ion pair abundance ratio as the qualitative judgment basis; liquid chromatography detection was used. The chromatographic peak area was used as the quantitative basis, and the external standard single-point method or the external standard standard curve method was used for quantitative analysis.

5 Reagents and Materials

5.1 Reagents The experimental water should meet the first-class water specified in GB/T 6682.Unless otherwise stated, the reagents used in the analysis were of chromatographic grade, Reagents include. a) methanol; b) Ethanol; c) n-hexane; d) isopropyl alcohol;
