Introduction: The APL-TD-100 automatic thermal desorption-desorption instrument is the fifth-generation automatic, dual-channel, up to 100 batch processing capacity, touch screen display, and more convenient operation. Thermal desorption apparatus. The gas circuit adopts the combination of electric valve and solenoid valve, and the touch screen is used to facilitate editing, saving, and calling the desorption, sampling and backflushing processes of the adsorption tube, which can clearly display the action status of each part of the sample extraction process, and the operation process of the instrument is clear at a glance . Features: 1. In order to facilitate the use, there is no need to use pneumatic means. The gas circuit adopts the combination of electric valve and solenoid valve to automatically realize the desorption, sample injection and backflush cleaning process; 2. The touch screen is used to facilitate editing, saving and calling methods, and up to 20 methods can be saved; 3. The heating temperature of adsorption tube heating, pipelines, valves, etc. can be set independently; 4. This machine comes with the function of standard sample simulation sampling, which can make the working curve through the thermal desorption instrument more conveniently; 5. Through time programming, automatic leak detection of 100 samples, dry blowing, primary desorption, secondary desorption injection, backwash cleaning, activation and other functions are automatically realized; 6. Simple-Lock locking and sealing technology is adopted to realize the simple and reliable fixing and sealing of the sampling tube, and the fixing and disassembly of the sampling tube can be completed in 2 seconds to realize efficient work; 7. Adopting semiconductor refrigeration, high cooling efficiency, no external refrigeration device is required, and cost saving; 8. Adopt international standard adsorption tube (length 1/4 inch about 89mm, outer diameter 3.5 inch about 6.4mm), the adsorption tube can withstand temperature of 420 ℃ and the adsorption tube is sealed with a sealed PTFE cap, which can ensure longer storage of samples time; 9. The injection needle is easy to replace and can be connected to all types of GC injection ports at home and abroad. Technical parameter: Temperature control range of desorption tube: room temperature—400℃, accuracy: 1℃; The temperature control range of valve sampling system: room temperature—220℃, accuracy: 1℃; Temperature control range of the sample transfer pipeline: room temperature—260°C, accuracy: 1°C; Primary analysis temperature range: room temperature—400℃, accuracy: 1℃ Secondary analysis temperature range: -35℃—400℃, secondary flash evaporation heating rate: >3000℃/min; Desorption recovery rate: >98% (related to components); Backflush cleaning flow: 0～100ml/min (continuously adjustable); One analysis flow: 0～100ml/min (continuously adjustable); Number of adsorption tubes: 100 positions
