1 Scope

This standard specifies the gas chromatography-mass spectrometry of acetophenone (CN) and o-chlorobenzylidene malononitrile (CS) in forensic science. Qualitative analysis method. This standard applies to the qualitative analysis of gas chromatography-mass spectrometry in the field of forensic science for the components of tear agents CN and CS in non-biological samples.

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. GA/T 242 Terms of physical and chemical testing for forensic science

3 Terms and definitions

The terms and definitions defined in GA/T 242 apply to this document.

4 Principle

The main targets of tear agents are the human eyes and skin, which can stimulate the human eyes, respiratory tract and skin. Lord of tears The main components are CN and CS. CN and CS are insoluble in water, but soluble in alcohol. Choose a solvent that easily dissolves CN and CS. The CN and CS components were extracted into the solvent and analyzed by gas chromatography-mass spectrometry.

5 Reagents and materials

The required reagents and materials are as follows. a) absolute ethanol (analytical purity); b) 0.1mg/mLCN standard solution; c) 0.1mg/mLCS standard solution; d) glass test tube; e) Micro syringe.

6 Instruments and equipment

Gas chromatography-mass spectrometer equipped with electron bombardment source (EI).

7 Sample preparation

For solid test materials, take a little sample, soak and extract with an appropriate amount of absolute ethanol reagent, and then use the concentrated extract as the test material extract for the instrument ......
