[0002] A nanoparticle size analyzer is an instrument that uses physical methods to test the size of solid particles. It mainly uses light scattering in liquids and photon-related spectroscopy technology to infer the size of particles in the liquid. In the prior art, the utility model patent application number 201720769770.1 discloses a nanoparticle size analyzer for chemical use. It mainly consists of a nanoparticle size analyzer body and an air pump. When in use, the liquid to be tested is injected into a test tube via the air pump. The test tube is then placed in the nanoparticle size analyzer, and the size of the particles in the liquid in the test tube is then detected by the nanoparticle size analyzer. The inventor believes that there are the following problems during use: because some solutions with higher concentrations to be tested contain a large number of bubbles, when the test solution containing bubbles is placed in the test tube, the bubbles in the solution will affect the scattering of light in the liquid, thereby affecting the nanoparticle size analyzer's detection accuracy of the particle size in the solution, making it inconvenient to use.
