Characteristics of GC-6890T high-purity gas chromatograph

The GC-6890T gas chromatograph is a newly designed micro thermal conductivity cell gas chromatograph that is computerized, self diagnostic, power-off protection, file storage and retrieval, extreme temperature setting, and shutdown protection.

1) Over temperature protection: When the actual temperature of each hot zone exceeds the set high value, the over temperature protection device works, automatically cutting off the power supply of each heating zone of the instrument, and sounding an alarm to avoid accidents.

2) Overcurrent protection: When the TCD detector is working, if the current is set too high or the TCD resistance suddenly increases, the overcurrent protection device will work, automatically cut off the TCD bridge current, and at the same time alarm and display OVER TCD to protect the tungsten wire from being burned out (if the user starts TCD without passing the load gas due to operational errors, the device can also automatically cut off the power to protect the tungsten wire). Amplification circuits can also be added to increase sensitivity.

3) Crash protection: When the instrument is in operation, it can automatically cut off the power and sound an alarm in case of short circuit or open circuit of the thermistor in each heating zone, grounding of the heating wire, or system crash of the microcomputer operating system, to avoid accidents caused by continuing to work. The above three protection functions can make your analysis work safer and more reassuring.

　　gas chromatographStreamlined appearance, novel, generous, beautiful, practical, reasonable structure, comfortable operation. It has gas cutoff protection function, which can protect chromatographic columns, thermal conductivity cells, electron capture detectors, etc. The anti-interference system will not affect the normal operation of the instrument in case of power fluctuations or momentary power outages. Complete temperature overheating protection and platinum resistance open circuit and short circuit alarm functions ensure that the temperature does not get out of control. Powerful self diagnostic function, allowing users to easily know the cause and location of problems. Adopting FLASH memory system, data protection does not rely on batteries. Bus structure, modular design, concise structure, independent functions, easy to upgrade and maintain.
