Introduction: The thermal desorber is a multi-functional pre-concentration technology combined with gas chromatography, which is used to analyze volatile and semi-volatile organic compounds in a variety of samples. By extracting volatile organic compounds from the sample and concentrating them into a very small volume of carrier gas, thermal desorption greatly enhances the sensitivity of trace target compounds, helps reduce interference, and is effective for ppb or lower concentrations. The analyte realizes routine detection. By realizing a series of fully automated operations such as sample preparation, desorption/extraction, pre-concentration, and injection into GC or GC-MS, thermal analysis greatly improves work efficiency. The ATD-12R secondary thermal analyzer is one of the company’s independent research and development and production of a variety of new series of products, with its unique functions and advanced nature, fully able to meet the new standard GB-50325-2020 "Civil Construction Engineering Indoor Environmental Pollution Control Standards" 》The analysis and testing requirements, with extremely low background, good repeatability, all linearity is better than 0.999, and the performance is stable and reliable. Features 1. Fully automatic one-button start, automatically complete the desorption and sampling analysis process of all adsorption tubes, without personnel on duty 2. Automatic leak detection, shunt without shunt function, electronic flow display and fault alarm function 3. Stable servo motor drive reliable hardware and software control system 4. Touch screen control, rich and complete interface information, simple operation 5. Method parameter setting, real-time display of working status and running time 6. Adsorption tube, injection valve, transfer tube, focusing tube (refrigeration, heating), all five channels can individually control the temperature 7. 10 methods for editing, storage and recall at any time, press the run button to automatically complete the sample analysis 8. Synchronously start GC/GCMS, and also use external event program to start the device to improve efficiency and reduce sample waste 9. High temperature six-way valve injection, which greatly reduces sample residue and ensures the sampling progress 10. The connection point between the six-way valve and the transmission pipeline is in the heating and incubator, and there is no cold spot for transmission, which ensures the integrity of the sample 11. This machine comes with the function of standard sample preparation, which can make the working curve through the thermal analyzer more conveniently 12. Automatic monitoring of the service life of the focusing tube 13. Lower cooling temperature and higher heating rate to ensure narrow chromatographic peak shape Technical parameter: Adsorption tube temperature control range: room temperature -400℃, temperature control accuracy: ±1℃ Six-way valve sampling system temperature and control range: room temperature -220℃, temperature control accuracy: ±1℃ Sample transfer tube temperature and control range: room temperature -220℃, temperature control accuracy: ±1℃ Focusing tube temperature control range: -40℃-450℃, heating rate>4800℃/min Cold trap temperature control range: -40℃-room temperature, using electronic refrigeration device, temperature control accuracy: ±1℃ Sample position: 12 digits Backflush flow: 0～100ml/min (continuously adjustable) Sample preparation flow: 100ml/min (continuously adjustable) Sample desorption, purging, injection and backflushing time: 0.0min～999.9min Adsorption tube specifications: diameter: 1/4 inch, length: 3.5 inches Power: 900W Power supply: 220V 50Hz
