ATD03 automatic primary thermal desorption desorption instrument Introduction: The ATD03 Automatic Thermal Desorption Desorption Instrument is a fully automated and computer-controlled intelligent primary thermal desorption instrument independently developed and launched by our company. The gas circuit adopts a combination of pneumatic six way valve and electromagnetic valve, and uses computer software to directly edit, save, and call up the desorption, injection, and backflushing processes of the adsorption tube. It can clearly display the action status of various parts during the sample extraction process, and the user can have a clear understanding of the instrument operation process. The heating temperature of the adsorption tube, six way valve, pipeline, and other components can be independently set, and a synchronous signal can be output during sample injection, enabling simultaneous start-up of chromatography and workstation. The product meets the requirements of thermal desorption instrument in GB50325-2020 Code for Indoor Waste minimisation of Civil Building Engineering, HJ 583-2010 Determination of Benzene Series in Ambient Air Solid Adsorption/Thermal Desorption Gas Chromatography and other standards. Features: 1. The gas circuit adopts a combination of pneumatic six way valve and electromagnetic valve to automatically achieve the process of desorption, sample injection, and back blowing cleaning 2. Adopting a computer controlled thermal desorption device, the method can be easily edited, saved, and called up, enabling quick operations such as one click testing and one click cooling 3. The heating temperature of the adsorption tube, pipeline, six way valve, etc. can be independently set 4. This machine comes with a standard sample simulation sampling function, which makes it more convenient to create working curves through a thermal desorption instrument 5. Automatically achieve functions such as desorption, purge adsorption, sample injection, and backwash cleaning (activation) through time programming 6. Adopting Tet-Lock locking and sealing technology to achieve simple and reliable fixation and sealing of the sampling tube, and completing the fixation and disassembly of the sampling tube in 2 seconds to achieve efficient work 7. Using 6 * 150mm standard tube or international standard tube (89mm long and 6.4mm outer diameter), the adsorption tube can withstand a maximum temperature of 420 ℃, and the adsorption tube is sealed with a sealed PTFE cap to ensure longer sample storage time 8. The replacement of the injection needle is convenient, and it can be connected to all models of GC injection ports both domestically and internationally 9. Standard input and output interface, which can communicate with any chromatograph and enable the start and stop of the chromatograph Technical parameters: Temperature control range of the desorption tube: room temperature -400 ℃, accuracy: 0.1 ℃ Temperature control range of valve injection system: room temperature -220 ℃, accuracy: 0.1 ℃ Sample transmission pipeline temperature control range: room temperature -260 ℃, accuracy: 0.1 ℃ Desorption recovery rate:>98% (related to components) Control system: fully computerized reverse control thermal desorption Blowback cleaning flow rate: 0-600ml/min (continuously adjustable) Simulated sampling flow rate: 100ml/min Instrument size: 450 × three hundred and sixty × 510mm Instrument weight: approximately 30kg
