Five types of fenpromethrin in forensic scientific biological materials
Examination of pyrethroid pesticides and their metabolites
Liquid chromatography-mass spectrometry
1 Scope
This standard stipulates for deltamethrin, cypermethrin, deltamethrin, etc. in forensic scientific biological materials (blood, urine, liver, kidney, stomach and stomach contents, etc.)
Qualitative and quantitative analysis of fenvalerate, permethrin and its common metabolite 3-phenoxybenzoic acid (3-PBA) by liquid chromatography-mass spectrometry (LC-MS)
method.
This standard applies to the fenpromethrin, cypermethrin, deltamethrin, fenvalerate, cypermethrin, and 3-PBA in forensic biological samples
Qualitative analysis and quantitative analysis. Other suspicious samples of deltamethrin, cypermethrin, deltamethrin, fenvalerate, permethrin and 3-PBA
Qualitative analysis and quantitative analysis can refer to use.

3 Terms and definitions
The terms and definitions defined in GA/T 122 Nomenclature for Toxicology Analysis 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 liquid color
Spectral-mass spectrometric quantification, based on retention time, mass spectrometry ion and relative abundance ratio as qualitative judgment basis; based on peak area,
The internal standard method was used for quantitative analysis.
5 Reagents and instruments
5.1 Reagent
The experimental water shall comply with the first-grade water specified in the GB/T 6682 analytical laboratory water specifications and test methods. Unless otherwise stated, at
The reagents used in the analysis are all analytically pure, and the reagents include.
a) Methanol (chromatographically pure);
b) Acetonitrile (chromatographically pure);
c) 5mmol/L ammonium acetate solution. Weigh 0.385g ammonium acetate, add water to bring the volume to 1000mL, and mix well;
d) 0.1mol/L hydrochloric acid solution. measure 9mL of concentrated hydrochloric acid, add water to bring the volume to 1000mL, and mix well;
