Description

Technical Field

[0001] The utility model relates to the technical field of phthalic anhydride determination, in particular to a determination mechanism for phthalic anhydride in sediments. Background Art

[0002] The determination mechanism of phthalic anhydride in sediment is mainly used for the analysis and detection of phthalic anhydride and other organic substances in ground sediments in polluted areas. The main components of the mechanism include solid phase extraction column group, solvent distiller, negative pressure sampling pump, environmental piping components, pollutant separation and extraction device and gas chromatograph.

[0003] 1. The solid phase extraction column group is used for sample extraction and concentration; 2. The main function of the solvent distiller is to dissolve organic matter in an organic solvent for subsequent concentration and separation; 3. The negative pressure sampling pump can sample sediment samples at different locations by inhaling airflow; 4. The environmental piping components mainly play a connecting role, connecting the various components into a whole to ensure the air tightness between the various components; 5. The pollutant separation and extraction device separates and extracts organic matter in the sample. During the separation and extraction process, phthalic anhydride is separated and extracted and prepared into samples that can be analyzed by gas chromatograph; 6. The gas chromatograph is used for quantitative analysis of concentrated and extracted samples. Through processing and testing at each link, the agency can accurately determine the content of organic matter such as phthalic anhydride in sediments, providing a scientific basis for environmental governance and prevention in polluted areas.

[0004] According to the above introduction, in the prior art, a variety of instruments and equipment are needed to determine phthalic anhydride in sediments, and the final quantitative analysis of phthalic anhydride still needs to be detected by gas chromatograph. Publication No. CN220730136 U discloses a high-precision gas chromatograph, in which a shock absorber and a spring cooperate with each other to reduce the vibration of the gas chromatograph body, thereby avoiding objects from leaking from the container. The buffer block squeezes the gas chromatograph body to prevent the gas chromatograph body from moving in the base, thereby reducing vibration.

[0005] The above-mentioned prior art realizes shock absorption by "fixedly connecting two shock absorbers 18 to the inner walls on both sides of the base 10, one end of the two shock absorbers 18 is fixedly connected to the same abutment plate 12, and the shock absorbers 18 are provided with springs". However, this method has the following problems: first, the shock absorbers are arranged on both sides of the base, and shock absorption can only be performed when the gas chromatograph moves horizontally. When the gas chromatograph is actually working, it will also vibrate in the longitudinal direction, and it may even be more obvious in the horizontal direction, and the above-mentioned prior art cannot perform shock absorption in the longitudinal direction. Secondly, shock absorbers are fixed on both sides of the base. When the abutment plate moves in a certain direction, although the shock absorber on one side can play a shock absorbing role, the shock absorber on the other side will affect the movement of the abutment plate, thereby reducing the shock absorption effect of the shock absorber that can play a shock absorbing role to a certain extent. Utility Model Content

[0006] The purpose of this section is to summarize some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments.

Secondly, shock absorbers are fixed on both sides of the base. When the abutment plate moves in a certain direction, although the shock absorber on one side can play a damping role, the shock absorber on the other side will affect the movement of the abutment plate, thereby reducing the damping effect of the shock absorber that can play a damping role to a certain extent.
