4 Principles

Seven cathinones such as 2-MMC in the suspected drug samples were extracted (see Appendix A for compound information). liquid color The qualitative detection was carried out by mass spectrometry, and the quantitative detection was carried out by liquid chromatography. The chromatographic peak area was used as the quantitative basis, and the external standard single-point method or external standard standard was used Quantitative analysis by curve method.

5 Reagents and Materials

5.1 Reagents The experimental water should meet the first-class water specified in GB/T 6682.Unless otherwise stated, the reagents used in the analysis were chromatographic Pure, reagents include. a) methanol; b) Formic acid-ammonium acetate buffer solution (taking 1000 mL as an example). Weigh 154 mg of ammonium acetate, dissolve it in.200 mL of water, and measure Acid 1.0mL, dropwise into the above ammonium acetate solution, transferred to a 1000mL volumetric flask to make up with water, and pumped with a vacuum filter pump
