What is the working principle of chromatographic analyzer?

Answer:

Is the gas chromatographic analyzer as mobile phase (carrier gas). When the sample is injected by a micro syringe into the injector, the carrier gas is carried into a packed column or a capillary chromatograph. Because the sample component in the mobile phase chromatograph (gas phase) and stationary phase (liquid or solid) between the distribution or adsorption coefficient, in the flush of carrier gas, the components in the two phases are repeated allocation, make organizations are separated in the column, the components in the column isolated, and then connected to the column after the detector based on the physical and chemical characteristics of components, the components in order to detect. MESP-405 oil chromatography analyzer is an analytical instrument manufactured according to the above principle.
The central base type instrument is a chromatographic column box, the upper right side is a microcomputer temperature controller, on the right side of the lower part is a FID micro current amplifier, instrument left flow control components and pneumatic panel, pillar box at the top right part is ionization detector installation location (basic installation of two flame ionization detector) and thermal conductivity detector (TCD) the installation location is double column box above the left column injector or capillary injector.
Host structureMESP-405 oil chromatographic analyzer consists of flow control components, injector, chromatographic column box, detector, temperature control and detector circuit components, chromatography workstation and so on.
