Forensic Science Carbon Particle Reagent Reveals Sticky Side of Tape Handprint technical specifications

1 Scope

This standard specifies the method, applicable objects, equipment, reagents, environmental requirements and operating procedures for the carbon particle reagent to display the sticky surface of the tape. This standard is applicable to the display of potential fingerprints on the adhesive surface of most tapes.

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 144 Forensic Science Fingerprint Terminology

3 Terms and definitions

The terms and definitions defined in GA/T 144 and the following apply to this document. 3.1 Carbonic particle reagent A suspension mainly composed of carbon particles, stabilizers and water.

4 Appearance principle

The carbon particles in the carbon particle reagent are fine, black, and have an adsorption force.The use of carbon particles adsorbs the difference between the handprint line and the adhesive surface of the tape. The carbon particles adsorbed on the handprint lines show the handprints. 5 Equipment, reagents, environmental requirements 5.1 Equipment Bamboo tweezers, brushes, utensils, water, cameras, etc. 5.2 Reagent Carbon particle reagent. 5.3 Environmental requirements Sanitary, clean and well ventilated.

6 Operation steps

6.1 Reagent validation Before using carbon particle reagents to display the sticky surface fingerprints on the tape, the carbon particle reagents and the similar tape adhesive surface fingerprints should be validated. ......
