1.Introduction
The gas chromatography is equipped with an automatic gas flow control module in the inlet, detector, and auxiliary gas module. The hydrogen flame ionization detector can be automatically ignited, hydrogen leakage is automatically protected, and it is safe and reliable. The special ceramicized amplification board is always stable in the wet season.
The gas chromatography is equipped with fully imported gas and liquid valves, which can be automatically controlled, sequence operation, stable performance and convenient operation. The current mainstream imported capillary chromatographic column is used in the scheme configuration, which has excellent performance and long service life, can achieve good separation effect and peak shape, and improve the accuracy and stability of analysis.

Instrument control and monitoring, method editing and storage
The chromatographic workstation Panna ChemLab communicates with the chromatograph through a networked interface, which can fully control all the parameters of the gas chromatograph, such as temperature, pressure, flow, split ratio, and the operation of valves and autosamplers. It can ensure the accuracy of each parameter setting. The stability of the test method. The editing, creation, modification, saving and recall of the method can all be carried out on the chromatographic workstation without any parameter setting on the instrument host, which is simple, convenient and easy to use, efficient and accurate. The Chinese keyboard monitors the working status of the instrument in real time.
The core of the software version adopts multi-threaded processing mode, so that instrument control, data acquisition, data processing and other application software running at the same time will not interfere with each other, and the stability of the system is greatly improved.
Instrument failure and maintenance can be automatically recorded by the built-in electronic tracking system
A91 GC machine has a built-in fault feedback and diagnosis system, which can track and automatically record the working conditions, faults and maintenance of the instrument in real time, providing a strong basis for the maintenance and troubleshooting of the instrument.
