Description

Technical Field

[0001] The utility model relates to the technical field of pollution particle observation and testing, in particular to a pollution particle observation and testing device. Background Art

[0002] The primary methods for observing and testing contaminant particles include microscopy, light scattering, and beta-ray analysis. In addition to these methods, other testing methods exist, such as screening and laser particle size analysis. Laser particle size analysis is a widely used and promising particle size measurement device. When light passes through an inhomogeneous medium, it deviates from its linear propagation direction due to the combined effects of absorption, reflection, refraction, transmission, and diffraction. The scattered light contains information about the size, shape, structure, composition, and concentration of the scatterer. Therefore, light scattering technology can be used to measure the concentration distribution and refractive index of a particle population, as well as the size distribution of the particle population.

[0003] In the existing technology, when using a laser particle size analyzer, the particles to be observed need to be placed into a sample cell through a feed tube. The instrument will analyze and determine the size distribution of the particles through the scattered light signal. There is no good self-cleaning measure for each use of the sample cell. During the observation test, some particles adhere to the inner wall of the sample cell and are not completely cleaned, which affects the accuracy of the device's next particle detection observation.
