4 Principles

The α-PBP, α-PVP and 4-F-α-PVP (compound information see Appendix A) in the suspected drug samples were extracted by gas chromatography. Spectral-mass spectrometry detection is based on retention time, characteristic ion fragmentation and ion abundance ratio as qualitative judgment basis; gas chromatography is used for detection, chromatographic The peak area was used as the quantitative basis, and the quantitative analysis was carried out by the external standard single-point method or the internal 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) Internal standard. tribenzylamine; c) Standard solution. 1) Standard material stock solution. α-PBP, α-PVP and 4-F-α-PVP standard material stock solution, the concentration is 1.0mg/mL; 2) Standard working solutions are divided into the following five categories according to experimental requirements.
