The terms and definitions defined in GA/T 122 apply to this document:
4 principles
Demerol in the suspected drug (see Appendix A for compound information) was extracted: detected by liquid chromatography-mass spectrometry
The characteristic ion pairs and ion pair abundance ratios of mass spectrometry were used as the basis for qualitative judgment; liquid chromatography was used for detection, and the peak area of the chromatogram 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
The experimental water should meet the first-class water specified in GB/T 6682: All reagents used in the analysis were chromatographically pure: Reagents include:
include:
a) Acetonitrile;
b) Methanol;
c) 20mmol/L ammonium acetate solution containing 0:1% formic acid (take the preparation of 1000mL as an example): Measure 1:0mL formic acid, weigh
1:542g of ammonium acetate, dissolved in water and adjusted to 1000mL, filtered with a vacuum filter pump, ultrasonic cleaner, and then
use;
d) 0:1% methanol solution of formic acid (take the preparation of 1000mL as an example): Measure 1:0mL of formic acid, dilute it with methanol and set the volume to 1000mL,
