4 Principles

Norephedrine, norephedrine, ephedrine, pseudoephedrine, methylephedrine and N-methyl-1- Phenyl-1-chloro-2-propylamine (see Appendix A for compound information) was extracted. Gas chromatography-mass spectrometry was used to detect retention time, characteristic ions and The ion abundance ratio was used as the basis for qualitative judgment; liquid chromatography-mass spectrometry was used for detection, and the retention time, mass spectral characteristic ion pairs and ion pair abundance ratios were used for detection. As the basis for qualitative judgment; liquid chromatography was used for detection, the chromatographic peak area was used as the quantitative basis, and the external standard single-point method or the external standard standard curve method was used. Perform quantitative analysis.
