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 Evenly mixed and ready to use: ......
