ATD25 fully automatic primary thermal desorption desorption instrument Introduction: The ATD25 fully automatic thermal desorption desorption instrument (25 positions) is a self-developed intelligent primary thermal desorption instrument with fully automated design and computer full reverse control operation. Added capillary focusing tubes to adsorb and focus the first resolved compound, followed by secondary thermal desorption, resulting in a more efficient injection efficiency. The pneumatic circuit adopts a combination of pneumatic six way valve and electromagnetic valve, and uses computer software to directly edit, save, and call 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 at a glance. The heating temperature of the adsorption tube, six way valve, pipeline, etc. can be independently set, and a synchronous signal can be output during sample injection, which can start the chromatography and workstation simultaneously. The product complies with the requirements of standards such as GB50325-2020 Code for Indoor Environmental Pollution Control of Civil Building Engineering and HJ 583-2010 Solid Adsorption/Thermal Desorption Gas Chromatography for the Determination of Benzene Series in Environmental Air. Features: 1. The pneumatic circuit adopts a combination of pneumatic six way valve and electromagnetic valve to automatically achieve desorption, sample injection, and backwash cleaning processes 2. Adopting a computer-controlled thermal desorption instrument, all methods can be easily edited, saved, and called up, and can achieve 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 the function of simulating sampling of standard samples, which makes it more convenient to create working curves through a thermal desorption instrument 5. Through time programming, automatically achieve functions such as desorption, blowing adsorption, injection, and backwash cleaning (activation) 6. Using 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. Adopting semiconductor refrigeration, high cooling efficiency, no need for external refrigeration devices, saving usage costs 8. Adopting an international standard adsorption tube (89mm long, 6.4mm outer diameter), the adsorption tube has a high temperature resistance of 420 ℃ and is sealed with a sealed PTFE cap, ensuring a longer storage time for the sample 9. Adopting the international standard hat removal disassembly scheme, abandoning the simple needle tying scheme, the maintenance cost is 1/50 of the needle tying cost 10. Equipped with automatic leak detection function, it can achieve pipeline, refrigeration system, heating system, and graded leak detection to ensure safety. If a leak is found, the system will alarm and reflect it. If the customer is not next to the instrument and does not handle it, the instrument will interrupt operation and wait for customer maintenance 11. Equipped with automatic dry blowing function, effectively removing interference from moisture and CO2 in the sample 12. Primary separation, secondary separation, and multiple enrichment can be used to achieve detection of high and low concentration samples 13. Optional automatic internal standard addition, facilitating comparative testing of complex samples and effectively reducing the risk of peak judgment errors 14. The replacement of the injection needle is convenient, and it can be connected to all GC injection ports of domestic and foreign models 15. Standard input and output interface, capable of communicating with any chromatograph and enabling the start and stop of the chromatograph 16. The fast heating method using passivated alloy wire is fast and has a long service life Technical parameters: Number of analytical workstations: 25 Standard: One hot desorption 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 ℃ Joint temperature: room temperature -220 ℃, accuracy: 0.1 ℃ Secondary analysis temperature range: -35 ℃ -400 ℃ Secondary flash evaporation heating rate:>3000 ℃/min Desorption recovery rate:>98% (depending on the composition) Blowback cleaning flow rate: 0-600ml/min (continuously adjustable) Simulated sampling flow rate: 0-200ml/min (continuously adjustable) Function: Adopting a computer-controlled thermal desorption device, all methods can be easily edited, saved, and called, and can achieve quick operations such as one click testing and one click cooling Safety function: Equipped with automatic leak detection function, it can achieve pipeline, refrigeration system, heating system, and graded leak detection to ensure safety. If a leak is found, the system will alarm and reflect it. If the customer is not next to the instrument and does not handle it, the instrument will interrupt operation and wait for customer maintenance Anti interference: Equipped with automatic dry blowing function, effectively removing interference from moisture and CO2 in the sample Sample enrichment function: It can use primary separation, secondary separation, and multiple enrichment to achieve detection of high and low concentration samples Optional function: Automatic internal standard addition is optional, which facilitates comparative testing of complex samples and effectively reduces the risk of peak judgment errors Instrument size: 560 x 350 x 620mm Instrument weight: approximately 35kg
