4 Principles

Extract 2'-chlordiazepam and 4'-chlordiazepam from the suspected drugs (see Appendix A for compound information). Using gas chromatography-mass For spectrometric detection, the retention time, mass spectrum characteristic ions and ion abundance ratio are used as the basis for qualitative judgment; for gas chromatography detection, the chromatographic peaks are used for detection. The 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 Unless otherwise stated, the reagents used in the analysis were of analytical grade. Reagents include methanol and standard solutions. a) Methanol. b) Standard solution. 1) Standard material stock solution. After conversion according to the purity and salt type of the 2'-chlordiazepam and 4'-chlordiazepam standard materials, weigh each Appropriate amount, use methanol to prepare 1.0 mg/mL 2'-chlordiazepam and 4'-chlordiazepam standard material stock solutions respectively. Seal, store below -18℃, valid for 12 months, or use commercially available standard solutions. 2) Standard working solutions are divided into the following four categories according to experimental requirements. ......
