Four sulfonylureas, such as metsulfuron, in forensic blood
Herbicide inspection
Liquid chromatography and liquid chromatography-mass spectrometry
1 Scope
This standard specifies the high-performance liquid chromatography (HPLC) quantitative detection of metsulfuron, bensulfuron-methyl, thisulfuron-methyl, and sulfasulfuron-methyl in forensic blood.
Test method and liquid chromatography-mass spectrometry (LC-MS) qualitative and quantitative test method.
This standard applies to the qualitative and quantitative analysis of metsulfuron, bensulfuron-methyl, thisulfuron-methyl, and sulfasulfuron-methyl in forensic blood. Other available
The qualitative and quantitative analysis of metsulfuron-methyl, bensulfuron-methyl, thisulfuron-methyl, and sulfasulfuron-methyl in suspected samples can be used for reference.
2 Normative references
The following documents are essential for the application of this document. For dated references, only the dated version applies to this article
Pieces. For the cited documents without date, the latest version (including all amendments) applies to this document.
GB/T 6682 Analysis laboratory water specifications and test methods

3 Terms and definitions
The terms and definitions defined in GA/T 122 apply to this document.
4 Principle
With blank samples and added samples as controls, according to the requirements of parallel operation, the blood is extracted, purified and concentrated, using high-performance liquid color
Quantification by spectrometry, legal quantification by liquid chromatography-mass spectrometry, with retention time, characteristic ions of mass spectrometry and relative abundance ratio as qualitative judgment basis;
Based on the peak area, the external standard method was used for quantitative analysis.
