I. Main performance characteristics:
      1. 320 x 240 dot-matrix 5.7-inch large-screen LCD Chinese display, real-time display of each temperature and operating conditions, perfect online monitoring;
      2. Power-on self-test, six-way independent temperature control (individual temperature control in vaporization chamber and capillary vaporization chamber), seven-step program temperature increase function;
      3. Wide-range self-diagnostic function. When the instrument fails, it will automatically display the fault phenomenon, fault code, cause of the fault, help to find and resolve the fault as soon as possible, and ensure the best working condition of the laboratory
      4. Over-temperature protection expansion function: If any channel exceeds the set temperature, the instrument will automatically power off and alarm;
      5. Carrier gas cutoff and leak protection functions. When the carrier gas pressure is insufficient, the instrument automatically cuts off the power and stops heating, effectively protecting the column and the thermal conductivity detector from damage;
      6. The door opening system after intelligent fuzzy control automatically tracks the temperature and dynamically adjusts the damper angle, enabling precise temperature control even near room temperature;
      7. Equipped with packed-column head sampling, glass-lined sampling, capillary splitting and splitless sampling device with diaphragm cleaning function, and gas sampler can be installed;
      8. High-precision dual-stable gas path, and up to four detectors can be installed at the same time;
      9. Advanced gas path process, can realize the simultaneous use of hydrogen flame detector and thermal conductivity monitor;
      10. Eight-way external event function supports multi-valve switching;
