Introduction: ATDS-3440 A/B secondary automatic/semi-automatic thermal analysis sampler is not only suitable for advanced laboratories of scientific research institutes, but also for those specialized fields (environmental monitoring, food and beverage, safety and forensic criminal investigation, cosmetics, agriculture, etc.) As a matching selection of conventional analysis or monitoring instruments. At the same time, it is also favored by postgraduates, doctoral students/post-completed thesis experiments/analysis in universities with relevant analysis. It is worth pointing out that due to the design concept of the ATDS-3440 A/B secondary automatic/semi-automatic thermal desorption sampler, if there is customer demand, it can be upgraded to a triple (secondary focus) full-automatic/semi-automatic thermal desorption sampler or Special sample pre-processing sampling device, etc. Features: 1. Open, functional module/unit combined design concept, realizes the technical sharing, co-construction and win-win between manufacturers and customers; 2. The non-rotating valve switching multi-dimensional gas path sampling system completely overcomes the 7 shortcomings of domestic six-port and ten-port valves, including short life; 3. The design of the gas path process is very simple, reliable, good for leak prevention, and greatly improves work efficiency. 4. The desorption tube is installed in the same direction as the air inlet and outlet, and the air drive is used to achieve double-needle connection, which is simple, intuitive, easy to prevent leakage, leak detection and maintenance; 5. If equipped with EPC (or Honeywell pressure sensor), it can realize the functions of automatic pneumatic system leak detection, special fault alarm, and conversion of different sample processing procedures; 6. In addition to the use of standard quantitative tube for sample injection, the sample injection time has been increased to adjust the sample volume; 7. For the sample transfer part, firstly, PEEK and 0.53mm elastic quartz capillary materials are popularized in China. In addition, the part processing in the sample transmission is optional and the processing time can be set; 8. Full-color screen display, friendly interface, touch operation, can be quickly and easily mastered, the whole process of tracking display operation process, set parameter values and real-time values, etc.; 9. ATDS-3440 A/B secondary automatic/semi-automatic sample thermal analysis sampler can be converted to a primary thermal sampler at any time. In addition, it can be regarded as a GC analysis sample pre-processing sample injection platform, as long as appropriate Adding or subtracting function modules can realize additional sample processing functions such as: blowing N2 concentration, simulated PTV injection, etc.; Technical parameter: 1. One-time desorption temperature adjustment range: room temperature～380℃, accuracy ±0.5℃, increment 1℃ optional 2. Two (three) desorption temperature adjustment range: room temperature ~ 380℃, accuracy ±0.5℃, optional increment of 1℃, heating rate >250℃/min 3. Focusing cold trap 1 (2) temperature adjustment range: room temperature～-40℃ accuracy ±1℃ increment 1℃ arbitrary setting 4. Temperature adjustment range of sample-related pipelines: room temperature～150℃, accuracy ±1℃, increment 1℃ optional 5. Position processing during sample transfer: optional, programmable, adjustable flow, temperature and time (such as: backflushing sample transfer, activation/aging of collection tube, etc.); 6. Controllable number of foreign affairs: 7 7. Foreign affairs time control range: 0.1～99 minutes Timing error: <0.1% 8. Material and specifications of sample collection tube: stainless steel/quartz glass, specifications (optional) 9. Collecting tube material and specifications: stainless steel, quartz glass, elastic quartz capillary, etc. (optional) 10. One-time thermal analysis flow: 0～100 ML/min continuously adjustable (with instructions) 11. Cylinder drive air pressure: <0.4MPa (adjustable) 12. Pressure resistance of gas circuit and related parts:> 0.4MPa 13. Number of samples processed in a batch: 12-24 14. Analysis accuracy: RSD <2.5% (related to GC performance and operation technology) 15. Instrument power: <1000VA 16. Linkage signal output switching time: <2 seconds 17. Apparatus dimensions: height×width×length 500mm×400mm×650mm 18. Weight: about 40 Kg
