Methoxycarb and methycarboxime in forensic biological samples
Inspection of gas chromatography-mass spectrometry and liquid chromatography-mass spectrometry
1 Scope
This standard specifies the gas chromatography-mass spectrometry (GC- mass spectrometry (GC-
MS) Qualitative test method and liquid chromatography-mass spectrometry (LC-MS) qualitative and quantitative test method.
This standard is applicable to the qualitative and quantitative analysis of metoprolol and metopoxime in biological samples. Among other suspicious samples
The qualitative analysis and quantitative analysis of dovixime can be used by reference.

3 Terms and definitions
The terms and definitions defined in GA/T 122 apply to this document.
4 Principle
Using blank samples and added samples as controls, according to the requirements of parallel operation, extract, purify and concentrate biological samples, using gas-phase color
Spectral-mass spectrometry qualitative, liquid chromatography-tandem mass spectrometry qualitative quantitative analysis, with retention time, characteristic ion fragment peak of mass spectrometry and relative abundance ratio
As the basis for qualitative judgment; based on the peak area, the external standard method was used for quantitative analysis.
