Abstract

The invention discloses a particle analysis device and particle sorting equipment. The particle analysis device comprises a detection light generation module used for generating detection light; the detection light generation module comprises a light source unit and a light adjusting unit, and the light adjusting unit is used for splitting light emitted by the light source unit into detection light with exchangeable wavelength and/or increasable and decreasable wave beams; and an optical detection module is used for analyzing an optical signal generated after the to-be-detected particles are irradiated by the detection light. According to the scheme of the invention, the wavelength of the detection light can be conveniently and flexibly adjusted.

Description

technical field [0001] Embodiments of the present invention relate to particle analysis technology, in particular to a particle analysis device and particle sorting equipment. Background technique [0002] Flow cytometry is a typical particle analysis and sorting device that relies on the flow of cells or other particles in a fluid flow stream to determine one or more characteristics of the particle under study. For example, the cells in the sample liquid are flowed and aggregated at the detection site through the high-speed sheath fluid, and one at a time passes through the detection site, and the cells at the detection site are irradiated by the detection light to generate forward and side scattered light. Labeled, can also produce the corresponding fluorescence. Cells are irradiated by laser light to produce small-angle forward scattered light and large-angle side scattered light in the same direction as the laser light, which respectively reflect the size and complexity...
