4 Principles

Prompt the acetone, ether, methyl ethyl ketone, chloroform, and toluene in the suspected precursor chemicals (see Appendix A for compound information). Pick. Gas chromatography-mass spectrometry was used for detection, and retention time, mass spectrum characteristic ions and ion abundance ratio were used as the basis for qualitative judgment.

5 Reagents and materials

5.1 Reagents Unless otherwise stated, the reagents used in the analysis are of chromatographic grade and include. a) Anhydrous sodium sulfate. analytical grade; b) methanol; c) Standard solution. 1) Standard material stock solutions. standard material stock solutions of acetone, diethyl ether, methyl ethyl ketone, chloroform, and toluene; 2) Standard working solution. Pipette an appropriate amount of standard material stock solution, dilute it with methanol, and prepare 0.1 mg/mL acetone and acetone respectively. Standard working solution of diethyl ether, methyl ethyl ketone, chloroform and toluene, refrigerated at 0℃~4℃, valid for 1 month; also Qualitative standard working solutions of other concentrations used in experiments can be prepared according to actual conditions. 5.2 Materials Materials include.
