[0002] Particulate matter detection is a detection technology that uses physical or optical methods to determine the concentration, size, and distribution of tiny particles in media such as liquids and gases. Particulate matter detection plays a crucial role in ensuring product quality, environmental safety, and human health by quantitatively and qualitatively analyzing particulate pollutants in the media, and is widely used in environmental monitoring, industrial manufacturing, and other fields.

[0003] When performing particulate matter detection, various detection methods can be used. Among them, liquid extraction is suitable for measuring particulate matter in liquids. By mixing the liquid to be tested with a solvent, the particulate matter is transferred from the liquid to the solvent. Then, equipment such as centrifuges can be used to precipitate the particulate matter, and it can be observed and counted using microscopes or other methods. However, this method requires the use of centrifugal rotation for precipitation treatment. If this work is not conveniently located, it can cause inconvenience to the staff. Utility Model Content
