Features: 1. Compared with similar products, AutoTD 20A innovatively uses 360-degree cylindrical heating technology in the first-level analysis, which allows the sample tube to be directly attached to the heater, and the first-level analysis is faster and more efficient. 2. AutoTD 20A uses the invention patent "hot air flow instantaneous analysis technology" in the secondary analysis, the cold trap analysis speed is faster, the sample enters the gas phase color faster, the peak shape of the analyte is sharper, and the instrument sensitivity is higher, especially The degree of separation of low-boiling components is also better. 3. AutoTD 20A has a high degree of automation, can automatically remove the cap and cap of the sample tube, automatic leakage test, automatic water vapor purging, and has a remote control function. 4. Compared with existing products, AutoTD 20A is designed with 20 sample positions, and the price is lower, which is suitable for customers with less sample volume. Technical Parameters: Operation mode: two-stage desorption (the first-stage desorption is focused on the cold trap, and then the cold trap is quickly desorbed in the second stage). The sample tube activation function adopts the international standard sample tube. Adsorption focusing method: fixed-point focusing. Desorption method: reverse blowing desorption, first stage 360℃ heating desorption, cold trap second stage hot air flow instantaneous desorption Sample capacity: 20 tubes First-level desorption: Temperature range: 50-390℃, step length is 1.0℃ Desorption time: 1.0-999min, step length: 0.1min Secondary desorption: Low temperature setting range of cold trap: -40℃-50℃, increment 1.0℃, electronic refrigeration method is adopted, no liquid refrigerant is needed High temperature setting range: 50℃-400℃, increment 1.0℃. Heating rate: real and instantaneous desorption of hot air flow Sample transmission: transmission line 1.2 meters, transmission temperature 250 ℃ Half peak width: <3S Desorption rate: >98% (0.1ul ethyl acetate split 100*100)
