After pretreatment, it was detected by gas chromatography-mass spectrometry, compared with the standard substance, and the retention time, characteristic ions and ion abundance ratio were used as judgments. Based on qualitative analysis.5 Reagents and materials5.1 Reagents All reagents used are of analytical grade, including. a) methanol; b) acetonitrile; c) Standard solution. 1) 1.0mg/mL standard substance stock solution. after conversion according to the purity and salt type of the standard substance, weigh an appropriate amount of methanol (or ethyl alcohol) nitrile) were prepared into 1.0mg/mL standard substance solutions of narcotic drugs and psychotropic drugs, sealed and placed in the refrigerator for freezing Save, valid for 12 months; 2) 0.1 mg/mL standard working solution. Pipette 1.0 mL of each 1.0 mg/mL standard material stock solution, add methanol (or nitrile) to 10mL, mix well, seal, store in the refrigerator, the validity period is 6 months; other concentrations used in the experiment ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GA/T 1920-2021_English be delivered?Answer: Upon your order, we will start to translate GA/T 1920-2021_English as soon as possible, and keep you informed of the progress.
