Introduction: ATDS-20B automatic dual-channel secondary thermal desorption instrument is a new generation product developed and launched by our company directly for the majority of users at home and abroad. This instrument is suitable for the qualitative and quantitative detection of various gases with boiling points below 350℃ in chemical building materials, food, atmosphere and indoor environments. It can be connected to any domestic and foreign gas chromatographs and gas-mass spectrometers. Its degree of automation, Indicators such as repeatability and sensitivity can fully meet the current environmental testing standards newly promulgated by the country, and it has its own unique functional advantages and satisfactory performance and price ratio in terms of structure. Fully automatic design, large touch screen display, more convenient operation, a new generation of automatic thermal desorption instrument that can continuously run 20 samples. Features: 1. It can automatically run double 20 samples (40 samples) without personnel on duty; 2. Power-on self-test, fault alarm and prompt, automatic positioning and calibration of the sample tray; 3. Computer USB communication interface, all parameters and methods are set on the PC side, 7-inch large-screen LCD touch screen, computer program control; 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, the functions of dry blowing, purge adsorption, desorption, sampling, backflushing, etc. can be automatically realized; 6. The gas path adopts passivation pipeline, and the sample transfer tube and injection valve have automatic backflushing function to avoid cross-contamination of different samples; 7. Electronic refrigeration and second-stage thermal desorption process are used to ensure narrow chromatographic peak shapes; 8. This machine comes with the function of standard sample analog sampling, which is convenient to obtain the working curve; 9. In order to be more convenient and accurate to use with imported gas chromatograph, this instrument is also equipped with special interfaces for various imported instruments, which is convenient to connect; 10. More than 20 editing methods, easy to edit, save and call; 11. Added Chinese and English switching, user management, log and other functions; Technical parameter: Desorption 1 temperature control range: room temperature-450 ℃, can be set arbitrarily in increments of 1 ℃; The temperature control range of the valve sampling system: room temperature—300°C, can be set in increments of 1°C; The temperature control range of the sample transfer pipeline: room temperature—300°C, can be set in increments of 1°C, and 24V low-voltage power supply is adopted; Desorption 2 temperature control range: room temperature-450 ℃, can be set in increments of 1 ℃; heating rate> 3000 ℃/min; The temperature control range of the cold trap: -35°C—room temperature, can be set in increments of 1°C, using semiconductor electronic cooling; Temperature control accuracy: <±0.5℃; Desorption recovery rate: >99% (related to the composition); Backflush cleaning flow: 0～100ml/min (continuously adjustable); Analog sampling flow: 0～160ml/min (continuously adjustable); RSD: ≤2.5% (0.05μg benzene in methanol); Enrichment time: 0～60min; Sampling time: 0～60min; Sample position: double 20 positions (40 positions); Sampling tube specification: 1/4 inch × 3.5 inch (American standard); Sampling mode: six-way valve motor drive; Instrument size: length×width×height=350mm450mm×550mm3; Instrument weight: about 40kg.
