3 Terms and Definitions
The terms and definitions defined in GA/T 122 apply to this document.
4 principles
The blank sample and the added sample were used as controls, and the paraquat in the biological inspection materials was extracted, purified and concentrated according to the requirements of parallel operations.
Liquid chromatography-mass spectrometry was used for qualitative and quantitative determination, and the retention time and characteristic ions of mass spectrometry were used as the basis for qualitative judgment; based on the peak area, the
