Foreword
This document complies with the provisions of GB/T 1:1-2020 "Standardization Work Guidelines Part 1: Structure and Drafting Rules of Standardization Documents"
Drafting:
This document replaces GB/T 29637-2013 "Gas Chromatography and Gas Chromatography-Mass Spectrometry Test Methods for Ketamine in Suspected Drugs" and is consistent with
Compared with GB/T 29637-2013, in addition to structural adjustments and editorial changes, the main technical changes are as follows:
---Changed the "scope" (see Chapter 1, Chapter 1 of the:2013 edition);
---Deleted the principle of gas chromatography method (see Chapter 4 of the:2013 edition);
---Added the principles of liquid chromatography and liquid chromatography-mass spectrometry methods (see Chapter 4);
---Deleted gas chromatography analysis reagents and reference materials, instruments and measuring instruments (see Chapter 5 of the:2013 edition);
--- Added reagents, instruments and materials for liquid chromatography and liquid chromatography-mass spectrometry (see Chapter 5);
---Changed the mass concentration of the gas chromatography-mass spectrometry qualitative quality control standard working solution (see 5:1:1:6, 6:1 of the:2013 version);
---Added liquid chromatography and liquid chromatography-mass spectrometry qualitative analysis (see 6:1:2 and 6:2);
---Deleted gas chromatography quantitative analysis (see Chapter 7 of the:2013 edition);
---Added liquid chromatography quantitative analysis (see Chapter 7);
---Changed the result evaluation (see Chapter 8, Chapter 8 of the:2013 edition):

3 Terms and definitions
The terms and definitions defined in GA/T 122 apply to this document:
4 Principles
Extract ketamine from suspected drugs (see Appendix A for basic information on ketamine): using gas chromatography-mass spectrometry and liquid chromatography
Method detection, based on gas chromatography-mass spectrometry retention time, mass spectrometry characteristic ions, ion abundance ratio and liquid chromatography retention time as the basis for qualitative judgment
According to the data; liquid chromatography-mass spectrometry is used for detection, and the retention time, mass spectrum characteristic ion pair and ion pair abundance ratio are used as the basis for qualitative judgment; using
For liquid chromatography detection, the chromatographic peak area is used as the quantitative basis, and the external standard single point method or the external standard standard curve method is used for quantitative analysis:
5 Reagents, instruments and materials
5:1 Reagents
5:1:1 Reagents for GC-MS analysis
Unless otherwise stated, the reagents used in the analysis were of chromatographic grade:
5:1:1:1 Methanol (CH3OH):
5:1:1:2 n-Hexane (C6H14):
5:1:1:3 Sodium carbonate (Na2CO3):
5:1:1:4 Anhydrous sodium sulfate (Na2SO4):
5:1:1:5 20% sodium carbonate aqueous solution (take the preparation of 100mL as an example): weigh 20g of sodium carbonate, dissolve it in water and adjust the volume to 100mL, mix
