1. Large screen LCD Chinese display, real-time display of various temperatures and operating conditions, clear and intuitive content, truly realizing human-machine dialogue;

2. Power on self-test, wide range self diagnostic function, can accurately determine the fault location and alarm;

3. Six independent temperature control channels (vaporization chamber and capillary vaporization chamber can independently control temperature), with eight step programmed temperature rise function;

4. Overtemperature protection function: If any circuit exceeds the set temperature, the instrument will automatically power off and sound an alarm;

5. The unique vertical heating device makes sample vaporization more reliable, minimizes the heat radiation generated by the vaporization chamber, and ensures minimal temperature deviation inside the column box;

6. Intelligent fuzzy control rear door opening system, automatically tracks temperature and dynamically adjusts air door angle, truly achieving near room temperature operation

7. Configure a capillary split/non split injection device with filling column head injection and glass lining injection, equipped with diaphragm cleaning function, and capable of installing gas injectors;

Can you believe it? This seemingly ordinary instrument can actually detect whether formaldehyde is present in grains. This is our independently developed GS series meteorological chromatographic analyzer, which is widely used in various fields

Used for safety testing in fields such as grain, food, and medicine.

Its core component, the gas chromatography column, uses our independently developed high-temperature aging technique, which can effectively avoid the aging problem of the chromatography column and improve detection accuracy. Meanwhile, we also

Advanced electronic flow control technology has been adopted to make the gas flow more stable, further improving the accuracy of detection.In addition, we also provide customers with comprehensive surgical support

And the service ensures that customers can easily get started with the operation. Isn't that how awesome we are?
