Glyphosate and Glufosinate-ammonium test gas chromatography-mass spectrometry

1 Scope

This document specifies the gas chromatography-mass spectrometry (GC-MS) method for the determination of glyphosate and glufosinate in biological samples (blood and urine) for forensic science applications. Inspection method. This document applies to the qualitative and quantitative analysis of glyphosate and glufosinate in biological samples (blood and urine) in the field of forensic science. Other samples may be used for reference.

3 Terms and definitions

The terms and definitions defined in GA/T 122 apply to this document.

4 Principle

Using blank samples and spiked samples as controls, the glyphosate and glufosinate ammonium (compounds) in blood and urine were measured in parallel. Basic information is shown in Appendix A) for extraction and derivatization, and gas chromatography-mass spectrometry detection is used to determine the retention time, mass spectrometry characteristic ions and ion abundance. The concentration ratio was used as the qualitative basis, and the chromatographic peak area was used as the quantitative basis, and the external standard method was used for quantification.

5 Reagents and Materials

5.1 Reagents The experimental water should comply with the third-grade water specified in GB/T 6682.The reagents used in the analysis are all analytical grade or above. include. a) methanol; b) Acetonitrile (newly opened or dehydrated with anhydrous sodium sulfate before use); c) Acetonitrile solution (for example, 90 mL). measure 60 mL of acetonitrile and 30 mL of water and mix well; d) 20% methanol-acetonitrile solution (taking 100 mL as an example). measure 20 mL of methanol and 80 mL of acetonitrile and mix well; e) Ammonia solution (taking 100 mL as an example). Take 97 mL of water and 3 mL of concentrated ammonia solution (mass fraction 25%~28%), Mix well; ......
