Gas chromatograph is an important instrument for the separation and determination of low boiling point mixed components. The gas chromatograph can be used for chemical analysis, biotechnology, and food specialty for instrument analysis experiments, but also for scientific research and routine analysis.
A gas chromatograph is an instrument that detects and analyzes gaseous substances or substances that can be converted to gas at a certain temperature. Due to the different physical properties of the material, the distribution coefficients of each component in the sample between the gas phase and the fixed liquid phase are different. When the vaporized sample is carried by the carrier gas into the chromatographic column for operation, the components are in two of them. Phases are repeatedly distributed between phases. Due to the different adsorption or dissolution capabilities of the fixed components, although the carrier gas flow rate is the same, the components run at different speeds in the column. After a certain period of flow, they are separated from each other. Leaving the column in sequence and entering the detector, the generated signal is amplified, and the chromatographic peaks of each component are traced on the recorder. According to the peak position, determine the name of the component, and determine the concentration based on the peak area. This is how the gas chromatograph works.
