Gas Chromatograph Feature:

  1. An intuitive 7-inch color touch screen providing digital displays for carrier/hydrogen/air channel flow (pressure) for easy monitoring.
  2. It has gas shortage alarm protection and heating control safeguards to ensure operational safety. The system automatically shuts down the column box fan motor and heating when the door is opened.
  3. Automatic control of split flow/split ratio optimizes carrier gas usage, reducing waste.
  4. It is tailored for various automatic samplers, with an installation and positioning interface for effortless compatibility.
  5. The gas chromatograph operates on a robust multi-core, 32-bit embedded hardware system, ensuring reliable and stable performance.
  6. It features a convenient one-button start function and 20 groups of sample test mode memory, enhancing operational efficiency and ease of use.
  7. Utilizes a logarithmic amplifier, ensuring a continuous detection signal with excellent peak shape. The system supports an external trigger function for synchronous start, activated by external signals like automatic samplers or thermal analyzers.
  8. Incorporates a comprehensive system self-check and automatic fault identification function, ensuring operational reliability.
  9. Offers 8 external event extension function interfaces, allowing customization with various control valves and sequence operations per user-defined time frames.
  10. It comes equipped with RS232 communication and LAM network ports, along with a configuration option for a data acquisition card, ensuring versatile connectivity and data acquisition capabilities.
