Liquefied petroleum gas chromatograph

1、 GC-3400 liquefied petroleum gas chromatographFunction Introduction:

1. Adopting a 320 × 240 dot matrix 5.7-inch ultra large LCD Chinese display, real-time display of various temperatures and operating conditions, achieving online monitoring;

2. Power on self-test, six independent temperature control (vaporization chamber and capillary vaporization chamber can be independently controlled), seven step programmed temperature rise function;

3. Wide range self diagnostic function: When the instrument malfunctions, it automatically displays the fault phenomenon, fault code, and fault cause in Chinese,

4. Assist you in finding and resolving faults to ensure the working condition of the laboratory;

5. Overtemperature protection function: The protection temperature can be set arbitrarily. If any circuit exceeds the set temperature, the instrument will automatically power off and sound an alarm;

6. Carrier gas cut-off and leakage protection function. When the carrier gas pressure is insufficient, the instrument automatically cuts off the power and stops heating, effectively protecting the chromatographic column and thermal conductivity detector from damage;

7. The intelligent fuzzy control rear door opening system automatically tracks temperature and dynamically adjusts the rear door opening angle, achieving precise temperature control even near room temperature;

8. 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;

9. High precision dual stable gas path, capable of installing up to four detectors simultaneously;

10. The gas path process can achieve the simultaneous use of hydrogen flame detector and thermal conductivity detector;

11. The eight channel external event function supports multi valve switching;

12. Optional electronic flow pressure display system and built-in workstation device

This chromatographic instrument can be installed with packed columns or capillary chromatography columns; And various detectors with different performance (TCD, ECD, FPD, NPD) can be selected and configured to form instruments with different performance. The instrument is controlled by a microcomputer, operated by a keyboard, and displayed on a LCD screen.
