Abstract

The invention discloses a miniature gas chromatograph for atmospheric pollution detection and relates to the technical field of meteorological chromatographs. The miniature gas chromatograph comprises a protective shell, wherein a roller is movably connected to the bottom of one side of the protective shell, a telescopic rod is movably connected to one side of the interior of the protective shell, and a rotating fluted disc is rotatably connected to the center of the top of the protective shell; guide rods are fixedly connected to two sides of an inner wall of the top of the protective shell, one end of each guide rod is sleeved with a rack, the other end of each guide rod is sleeved with a first compression spring, the racks are movably connected with the protective shell through the first compression springs, and one end of each rack is fixedly connected with a pull rod; and a second compression spring is fixedly connected into one end of the rack. According to the device, the door plate structure is arranged on one side of the protective shell, when the device is not used, the door plate can be closed, safety of the device is improved, the service life is prolonged, and when the device is used, the door plate can be opened to work normally.

Description

technical field [0001] The invention relates to the technical field of gas chromatographs, in particular to a micro gas chromatograph for air pollution detection. Background technique [0002] Gas chromatograph refers to a chromatographic analysis instrument that uses gas as a mobile phase. Its principle is mainly to use the differences in the boiling point, polarity and adsorption properties of substances to separate mixtures. The samples to be analyzed are gasified in the gasification chamber by inert gas (ie carrier gas, also known as mobile phase) is brought into the chromatographic column, the column contains 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. In the flow of gas, the sample components are repeatedly distributed or adsorbed / desorbed during the movement. The components with high distribution concentration in the carrier gas flow out of ...
