Description

Technical Field

[0001] The utility model relates to the technical field of medicinal material detection, in particular to a gas chromatograph for medicinal material detection. Background Art

[0002] Gas chromatograph refers to a chromatographic analysis instrument that uses gas as the mobile phase. Its principle is mainly to use the differences in the boiling point, polarity and adsorption properties of substances to achieve the separation of mixtures. After the sample to be analyzed is vaporized in the vaporization chamber, it is carried into the chromatographic column by the inert gas (i.e., carrier gas, also known as mobile phase). The column contains a liquid or solid stationary phase, and each component in the sample tends to form a distribution or adsorption equilibrium between the mobile phase and the stationary phase. As the carrier gas flows, the sample components are repeatedly distributed or adsorbed / desorbed during movement. The components with high distribution concentrations in the carrier gas flow out of the chromatographic column first, and the components with high distribution concentrations in the stationary phase flow out later. After the components flow out of the chromatographic column, they enter the detector for measurement. Commonly used detectors include electron capture detectors (ECD), hydrogen flame detectors (FID), flame photometric detectors (FPD) and thermal conductivity detectors (TCD).

[0003] At present, in the detection of medicinal materials, a gas chromatograph is needed to detect the medicinal materials. When the existing gas chromatograph is idle, a certain amount of dust will fall on its surface. If the dust is not cleaned in time and accidentally falls into the gas chromatograph, the service life of the components inside the gas chromatograph will be shortened, thereby affecting the service life of the gas chromatograph. In addition, the gas chromatographs on the market lack a device for cleaning the display screen after use. Over time, stains are easily generated on the surface of the display screen, affecting the user's observation. Therefore, it is necessary to propose a gas chromatograph for medicinal material detection to solve the above problems. Utility Model Content
