GB/T 6682 Analytical laboratory water specifications and test methods
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
Using the blank sample and the added sample as a control, according to the requirements of parallel operation, the 21 kinds of alkaloids (see Appendix A) in the biological samples were tested.
Extraction, purification and concentration were carried out, and liquid chromatography-triple quadrupole tandem mass spectrometry or liquid chromatography-high resolution mass spectrometry were used for detection.
5 Reagents and materials
