Forgas chromatographThere are no special requirements for the equipped printer. Laser printers and stylus printers can be used, but it is recommended to use a laser printer, and the printed report has better results.

Gas chromatograph is widely used in fire investigation, petroleum, chemical industry, biochemistry, medicine and health, food industry, environmental protection and other fields. In addition to quantitative and qualitative analysis, it can also determine the distribution coefficient, activity coefficient, The molecular weight and specific surface area of the sample on the stationary phase, as well as other physicochemical constants, are an instrument for the analysis and detection of components in mixed gases.

Gas chromatograph, after the analysis sample is evaporated in the sample inlet, the carrier gas is brought into the chromatographic column, and the components are separated by the chromatographic column. These components have different retention characteristics for the components in the mixture to be detected, Then the detector is introduced in turn to obtain the detection signal of each component. According to the order of introducing the detector, after comparison, each component can be distinguished, and the content of each component can be calculated according to the peak height or peak area. Commonly used detectors are: thermal conductivity detector, flame ionization detector, helium ionization detector, ultrasonic detector, photoionization detector, electron capture detector, flame photometric detector, electrochemical detector, mass spectrometer detector, etc.

Beijing Bei Fen Tianpu Instrument Technology Co., Ltd. has been committed to the establishment, application and promotion of chromatographic analysis methods for a long time. With years of experience in the field of gas chromatography applications, it provides users with an overall solution for chromatographic detection systems. I would also like to sincerely thank friends from all walks of life for their trust and support to Tianpu over the years. I hope we can continue to increase contact and develop together.
