Application
Mainly used for qualitative and quantitative analysis of unknown samples Monitoring of harmful substances in the environment

1. Military industry: monitoring of anti-chemical warfare, confined space on ships air and

pollution monitoring
2. Public security: drug monitoring, explosives detection
3. Chemical: detection of pure substances and impurities, monitoring of chemical process
4. Pesticide residues in Food
5. Food additives, such as: sorbic acid, benzoic acid, etc.
6. Carcinogens in food
7. Harmful residues in bakery products
8. Harmful residues in edible oil, wine, water and drinks
9. PVC in packaging materials
10. Methanol and vitamin-Ein cosmetics
11. Harmful residues in paint and dye
12. Health products
