Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. Please note that some content of this document may involve patents. The issuer of this document does not assume responsibility for identifying these patents. This standard was proposed by the National Criminal Technology Standardization Technical Committee Physical and Chemical Inspection Sub-Technical Committee (SAC/TC179/SC4) and Be in charge. This standard was drafted by. Material Evidence Appraisal Center of the Ministry of Public Security, Material Evidence Appraisal Center of Shanghai Public Security Bureau. The main drafters of this standard. Guo Hongling, Ding Minju, Wang Ping, Quan Yangke. Forensic soil elemental composition test X-ray fluorescence spectroscopy

1 Scope

This standard specifies the method of inspection and analysis of soil physical evidence by X-ray fluorescence spectroscopy in the field of forensic science. This standard is applicable to the comparison test of the elemental composition contained in the soil physical evidence in the field of forensic science. It can also be used by reference in other fields.

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

When the sample is irradiated with strong X-rays, the atoms of each component element are excited to produce secondary characteristic X-rays, namely X-ray fluorescence. Different elements have characteristic X-ray lines of different wavelengths, and the intensity of each line is in a certain degree with the concentration of the element Relationship, the wavelength and intensity of the characteristic X-ray spectrum of the element to be measured can be analyzed qualitatively and quantitatively. Mud is a mixture of minerals, organic matter and living organisms as well as moisture, air, etc., with minerals as the main component. Different soil The elemental composition and content of minerals are different. The X-ray fluorescence spectrometer can be used to analyze the elements in the soil sample, thereby Achieve inspection and comparison of soil element composition.

5 Reagents and materials

Boric acid (analytical purity).

6 Instruments and equipment

The required instruments and equipment are as follows. a) X-ray fluorescence spectrometer; b) grinding machine; c) Tablet press (with tablet mold), pressure range 20MPa~30MPa; d) oven; e) Balance, accuracy 0.1mg. ......
