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
Extract 17 characteristic impurities in ketamine samples. Liquid chromatography-mass spectrometry was used to detect the
The sub-pair and ion pair abundance ratio was used as the basis for qualitative judgment, and the quantitative ion pair chromatographic peak area was used as the quantitative basis. The analysis of 17 target substances was
After processing the analysis results, use the Pearson correlation coefficient method to determine the correlation between samples.
5 Reagents, instruments and materials
