Brief introduction: Thermal desorption instrument is a kind of sample pretreatment device, with gas chromatograph with or combined with GC/MS, etc. Organic compounds, minimum detectable concentration of PPB level even PPT. TP - 2030 type thermal desorption instrument is my company in 2004 to develop products with independent intellectual property rights, in the past ten years, has a large number of production and the market. Typical applications mainly include: civil engineering indoor environment pollution; Occupational safety, industrial hygiene and environmental monitoring; Quickly identify unknown atmospheric organic compounds; Flavors and fragrances smell analysis; Toxic environment accident assessment; Chemical weapons storehouses of perimeter environment monitoring; Polymers, packaging industry and building materials quality control tests; Hospital patient breath gas, analysis of volatile drug metabolites in the blood; Drugs solvent and product purity assessment; Drugs and the court the residue analysis of the sample Features: 1. The pressure balance principle, no valve, direct injection, dead volume for "zero" 2. You do not need to do any changes on the original GC, when with desorption on the samples directly from vaporizing chamber after injection, to eliminate the memory effect of the previous sample system 3. The desorption furnace adopts vertical portable structure, is suitable for the gas chromatograph with different manufacturer and model 4. The desorption heating furnace temperature, solution straw by inserting vaporizing chamber furnace, to maximize the adsorption of heating rate 5. The adsorption calibration simulation samples of suction time, desorption time, sampling time and so on, by the time the program control automatically 6. Leave the desorption furnace cooling solution straw, replacement can be conveniently in the desktop to complete the operation, simple and convenient 7. The liquid sample can be directly from the desorption of constant temperature heating stove top injection tube adsorption analysis, provides a new method of calibration 8. In addition to the direct online sample, according to different analysis requirements "needle tube sampling method is convenient for operation 9. Due to the operation principle of the different structure compared to similar domestic thermal desorption instrument, the minimum detectable concentration is lower, the linear range, the analysis precision and accuracy are easier to guarantee Technical parameters: Desorption furnace temperature control range: at room temperature to 400 ℃ Desorption furnace temperature control precision: plus or minus 0.2 ℃ Desorption pressure (flow) : 0-500 - ml/min calibration flow continuously adjustable Desorption time, sampling time, calibration sample time: 0-99 minutes Five programmable, continuously adjustable Large amount of sampling in the detection limit: < PPB level Solution straw heating rate: > 300 ℃ / min The desorption rate: 90% (and components) Beijing BJ01-91-91 standard testing, for example: when the TVOC precision (Tenax TA adsorption tubes, relative standard deviation) and accuracy (Tenax TA sample average 5 times) is superior to the standard.
