Description

Technical Field

[0001] The invention relates to the field of customs inspection coordinated with an Agile ENT 8700LDIR laser infrared imaging system, and in particular to a special continuous sample placement structure for monitoring laser infrared imaging microplastic testing. Background Art

[0002] The microplastics test in the Agilent 8700LDIR laser infrared imaging system is very mature, but during the on-site operation test, the following problems were found:

[0003] 1. After the current sample base is inserted into the sample chamber, the software will first scan the sample window as a whole to confirm the horizontality of the sample window so as to realize automatic scanning of the entire sample; to test the horizontality, LDIR will scan the window from the side. However, the Kevy window is only coated on the upper surface, so the light will pass through the entire window from the side and cannot achieve the purpose of the window horizontality test; therefore, it is recommended to blacken the right side of the window with a marker during operation. The current sample base structure is too complicated, and the glass slide needs to be taped up each time, otherwise the result will be tilted because it cannot be quickly straightened for monitoring. The structure is complicated and the cost is too high. And the problem of needing to be outlined with a marker.

[0004] 2. Currently, all microplastic detection instruments are single-channel sample injection. The replacement, fixation, and blackening of the slides consume a lot of time for the inspectors. As the problem of microplastic pollution becomes increasingly prominent, the importance of microplastic detection becomes more and more prominent, and the sample volume required for detection is also increasing. There is an urgent need for a special slide to solve the current time-consuming sample injection problem. Each slide is sampled separately, and basically one person is required to go in and out for 30 samples; this wastes manpower and consumes a lot of inspectors' time; it delays the inspection work.

[0005] As the Customs Technical Center becomes increasingly busy, and as microplastic pollution becomes more prevalent around the world, microplastics are found in basically all seawater and soil.

[0006] On May 9, 2024, with "microplastics and detection and sampling" as the abstract keywords, and the option to allow synonym expansion, a search was conducted in the Chinese Patent Publication Database, and seven documents were found: CN117269134A A microplastic sorting system and method based on dual fluorescence spectroscopy; CN115656347A A rapid detection method for microplastics in food; CN115469049A A qualitative and quantitative detection method for microplastics in aquatic shellfish; CN217981238U A portable device for online automatic detection of microplastics based on Raman spectroscopy; CN113325098A A synchronous analysis and detection method for microplastics and organic pollutants in soil; CN214121715U A detachable microplastic collection device suitable for various water depths; CN111896437A An indoor simulation device for measuring the movement rate of microplastics in water. These schemes do not have any continuous sampling design.

[0007] On May 9, 2024, an abstract search for "slide and detection and injection and continuous" was conducted on CNKI, and the following articles were found: "Effects and Mechanisms of Chemical Genetics Targeted Activation of Motor Cortex Glutamate Neurons on Motor and Cognitive Functions of Mice with Intracerebral Hemorrhage" and "Fabrication, Surface Modification and Application of Low-cost Polymer Electrophoresis Chips in Food Analysis". They are not related to this case.
