ATDS-6000D Thermal Analyzer

ATDS-6000D Thermal AnalyzerIt is a sample pretreatment device that can be used with all imported and domestic gas chromatographs. The detection concentration of volatile organic compounds in the environment can reach ppb level.ATDS-6000D Thermal AnalyzerIn addition to meeting the requirements of "Determination of Benzene in Indoor Air" and "Determination of Total Volatile Organic Compounds (TVOC) in Indoor Air" in GB50325-2020 "Code for Indoor Environmental Pollution Control of Civil Building Engineering", it can also be applied to the following fields:
1. Occupational safety, industrial hygiene, and environmental monitoring;
2. Rapid identification of unknown atmosphere;
3. Analysis of spices and essence;
4. Assessment of toxic substance accidents (when personnel can safely return to the accident site);
5. Perimeter environmental safety monitoring of chemical weapons warehouses;
6. Quality control testing in polymer and packaging industries;
7. Evaluation of drug solvents and product purity;
8. Residual analysis of drugs and court samples;
9. Collect exhaled gases from patients and detect volatile drug metabolites in their blood in hospitals.
