4 Principles

Extraction of methamphetamine in suspected drugs. Gas chromatography-mass spectrometry was used for detection, with retention time, mass spectrum characteristic ions and The ion abundance ratio is used as the basis for qualitative judgment; liquid chromatography-mass spectrometry is used for detection, based on retention time, mass spectrum characteristic ion pair and ion pair abundance. The ratio is used as the basis for qualitative judgment; gas chromatography is used for detection, and the chromatographic peak area (or peak area ratio) is used as the quantitative basis, and an external standard single point is used. method or internal standard standard curve method for quantitative analysis; liquid chromatography is used for detection, using the chromatographic peak area as the quantitative basis, and external standard single-point method Or external standard curve method for quantitative analysis. 5 Reagents, instruments and materials 5.1 Reagents 5.1.1 Reagents for GC and GC-MS analysis Unless otherwise stated, the reagents used in the analysis were of analytical grade. 5.1.1.1 Methanol. 5.1.1.2 Acetonitrile. 5.1.1.3 Extraction solvent. acetonitrile to water = 15 1 (volume ratio). 5.1.1.4 N-propylethylenediamine (PSA). 5.1.1.5 Anhydrous sodium sulfate. ......
