G51Pro high-performance gas chromatograph

The principle of gas chromatography:

gas chromatographIt is an analytical instrument used to determine the content of different components in a sample. The method of analyzing using gas chromatography is called gas chromatography.

After the sample solution is injected, it enters the vaporization chamber and then enters the chromatographic column under the transport of carrier gas (usually nitrogen or helium gas). Different components are separated in the chromatographic column and flow out of the column in sequence, which is detected by the detector to obtain their content. When determining the content of a certain component in a sample, it is necessary to first analyze a standard sample with a known concentration, and then compare the retention time and peak area of the chromatographic peak of the standard sample with the sample to be tested, and calculate the content of the target component in the sample to be tested.

Main features and performance indicators of high-performance gas chromatography:

1、G51ProHigh performance gas chromatographadopt7Inch color touch screen,can provideRS232Communication port andLANENetwork port.

2. Manual adjustment of gas path and fully electronic gas path（APC/AFC）Optional control, networked communication, computer online full control operation.
