1 Scope

This document specifies liquid chromatography-mass spectrometry (LC-MS) qualitative testing methods for 202 narcotic drugs and psychotropic substances in suspected drugs, including Contains liquid chromatography-tandem mass spectrometry (LC-MS/MS) and liquid chromatography-high resolution mass spectrometry (LC-HRMS). This document is applicable to the qualitative analysis of 202 narcotic drugs and psychotropic substances in solid samples suspected of drugs. suspected drug The test of narcotic drugs and psychotropic drugs of other samples of samples can be used as reference.

4 Principles

Taking advantage of the characteristics of drugs being easily dissolved in organic solvents, the detection of 202 kinds of narcotic drugs and psychotropic drugs (see Appendix A) in suspected drug samples After pretreatment, the material samples were detected by liquid chromatography-tandem mass spectrometry in multiple reaction monitoring (MRM) mode. The qualitative analysis was carried out based on the retention time (tR) and two pairs of parent ion/product ion pairs; liquid chromatography-high resolution mass spectrometry was used. Detect, compare with the reference material, and use retention time (tR), precursor ion, and a characteristic ion of secondary mass spectrometry as the basis for qualitative determination analyze.
