GA/T 122 Toxicological Analysis Terminology
3 Terms and Definitions
The terms and definitions defined in GA/T 122 apply to this document:
4 principles
Nimetazepam (see Appendix A for compound information) in suspected drug samples was extracted: Gas chromatography-mass spectrometry was used to detect
The retention time, characteristic ions, and ion abundance ratio were used as the basis for qualitative judgment; gas chromatography was used for detection, and the chromatographic peak area was used as the quantitative basis:
Quantitative analysis was carried out by external standard single point method or external standard standard curve method:
5 Reagents and materials
5:1 Reagents
Unless otherwise stated, the reagents used in the analysis are of analytical grade, including:
a) Methanol;
b) Standard solution:
1) Standard substance stock solution: Nimetazepam standard substance stock solution;
2) The standard working solution is divided into the following four categories according to the experimental requirements:
---Qualitative standard working solution: pipette an appropriate amount of nimetazepam standard substance stock solution, dilute with methanol, and prepare
0:1mg/mL Nimetazepam standard working solution, stored in refrigerator at 0℃~4℃, valid for 3 months;
---Qualitative quality control standard working solution: pipette an appropriate amount of nimetazepam standard substance stock solution, dilute with methanol, and prepare
0:002mg/mL Nimetazepam standard working solution, stored in cold storage at 0℃~4℃, valid for 1 month;
