The thermal analyzer is a sample pretreatment device in the gas chromatograph analysis and detection system. It mainly uses a physical method to heat and adsorb the sample, thereby purifying the sample.
So why do you want to pre-treat the sample? The benefits of sample pretreatment have two points: first, through purification, crystallization treatment, the equipment can be used to achieve the specified concentration; second, the impurities in the sample are removed to prevent impurities from affecting the accuracy of the sample detection results. It even blocks precision components in chromatograph equipment such as columns, six-way valves, loops, and more. Sample pretreatment is an essential part of both gas chromatograph and liquid chromatograph analysis.
In gas chromatograph sample processing, the thermal analyzer works by injecting the sample to be tested into a sorbent tube filled with an adsorbent (the filler in the adsorption tube of the thermal analyzer must be determined according to the nature of the sample being sampled. The adsorbent), wherein the volatile component is adsorbed and eliminated, and the remaining sample in the adsorption tube is heated to desorb the collected volatile organic compound, and the sample to be tested enters the capillary column gas chromatograph equipped with the flame ionization detector with the inert carrier gas. Analyze.
The thermal analyzer has the advantages of convenient sampling, quick inspection and accurate quantitative, and is widely used in the gas chromatograph analysis system. The automatic thermal analysis gas chromatograph meets the gas chromatographic detection and analysis of total volatile organic compounds (TVOC) and benzene in indoor air (this method complies with GB/T 50325-2010 "Code for Indoor Environmental Pollution Control of Civil Building Engineering" and HJ 583 -2010 "National Standard for Determination of Benzene in Ambient Air by Solid Adsorption/Thermal Desorption-Gas Chromatography"), it can also be applied to the following fields: 1. Occupational safety, industrial hygiene and environmental monitoring; 2. Unexplained atmospheric fast Identification; 3, analysis of fragrances and fragrances; 4. Assessment of toxic substance accidents (when personnel can safely return to the accident site); 5. Environmental safety monitoring of the perimeter of chemical warehouses; 6. Quality control testing in polymer and packaging industries; 7. Evaluation of drug solvent and product purity; 8. Residue analysis of drugs and forensic samples; 9. Collecting gas exhaled by patients in hospitals, and detecting volatile drug metabolites in blood.
