2,4-D, etc. in forensic scientific biological materials
Inspection of four phenoxycarboxylic acid herbicides
Gas chromatography and gas chromatography-mass spectrometry
1 Scope
This standard stipulates 2,4-D (2,4-dichlorophenoxyacetic acid, 2,4-) in forensic scientific biological materials (blood, urine, liver, kidney, stomach and stomach contents, etc.)
Drops), 2,4-DP[2-(2,4-dichlorophenoxy)-propionic acid, also known as 2,4-drop propionic acid], MCPA (4-chloro-2-methyl-phenoxyacetic acid, Also known as 2 A 4 chlorine)
And MCPP [2-(4-chloro-2-methyl-phenoxy)-propionic acid, also known as 2 methyl 4 chlorophenoxypropionic acid] Gas Chromatography (GC) of four phenoxycarboxylic acid herbicides
Quantitative test method and gas chromatography-mass spectrometry (GC-MS) qualitative and quantitative test method.
This standard applies to qualitative and quantitative analysis of 2,4-D, 2,4-DP, MCPP, and MCPA in forensic biological samples. its
The qualitative and quantitative analysis of 2,4-D, 2,4-DP, MCPP and MCPA in his suspicious samples can be used for reference.
