GA/T 103-1995Forensic sciences - Examination methods for five pyrethroid pesticides including fenpropathrin in biological samples - GC-MS (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard replaces GA/T 103-1995 "Qualitative and Quantitative Analysis Methods for Pyrethroid Pesticides in Poisoning Materials", and Compared with GA/T 103-1995, except for editorial changes, the main technical changes are as follows.

--- Modified the standard name (see cover, cover of 1995 edition);

--- Deleted the gas chromatography inspection method (see the first and second parts of the 1995 edition);

--- Deleted the TLC inspection method (see the third edition of the 1995 edition);

---Revised the content of reagents and materials (see Chapter 5, Chapter 5 of the 1995 edition);

---Revised the content of instruments and equipment (see Chapter 6, Chapter 6 of the 1995 edition);

--- Added the method of gel permeation chromatography concentration combined instrument (see 7.1.2.1.1);

--- Added gas chromatography-mass spectrometry test method (see 7.1.2.1.2).

1 Scope

This standard stipulates cypermethrin, lambda cyhalothrin, and cypermethrin in forensic biological samples (blood, urine, liver, kidney, stomach, and stomach contents, etc.) Qualitative and quantitative test method for gas chromatography-mass spectrometry (GC-MS) of pyrethrin, fenvalerate and deltamethrin.

This standard is applicable to fenpromethrin, lambda cyhalothrin, cypermethrin, fenvalerate, and deltamethrin in forensic biological samples Qualitative analysis and quantitative analysis. Other suspicious samples of cypermethrin, lambda-cyhalothrin, cypermethrin, fenvalerate and deltamethrin Qualitative analysis and quantitative analysis can refer to use.

4 Principle

Use blank samples and added samples as controls, and extract, purify, and concentrate biological samples in accordance with the requirements of parallel operation.

Spectral-mass spectrometry qualitative and quantitative. Qualitative judgment is based on retention time, mass ion characteristic ion fragment peak and relative abundance ratio; peak surface Based on the product, quantitative analysis was performed using the external standard method.
