Description
technical field [0001] The invention relates to the technical field of cutting efficiency of a sampler, in particular to a system and method for quickly measuring the cutting efficiency of a sampler. Background technique [0002] The cutter is an important part of the sampler. The cutting efficiency of the cutter is an important parameter of the sampler and the core part that affects the accuracy of the sampler's measurement results. Domestic research on the cutting efficiency of cutters started relatively late, and there is no perfect technology and standard for measuring the cutting characteristics of cutters in China. [0003] To measure the cutting efficiency of the cutter, it is necessary to measure the transmittance of particles with different particle sizes, and then obtain the cutting efficiency of the cutter by fitting the transmittance-particle size curve. [0004] The cutting efficiency of the traditional cutter is measured by fluorescence photometry: the monodis...
