Listed Instrument New Products in the First Half of 2010: Particle Size Meter

Particle size analyzer is a kind of instrument that uses physical methods to test the size and distribution of solid particles, and is widely used in construction, coatings, petroleum, medicine, environmental protection, food and other fields. From the perspective of the entire Chinese particle size analyzer market, its market capacity has exceeded 1,000 units, and in terms of quantity alone, the market share of domestic particle size analyzers has approached 80%.

In recent years, particle testing technology has progressed rapidly and particle size testing methods have reached more than 100 species. According to the different test principles, it is mainly divided into several categories: settlement type particle size analyzer, settlement balance, laser particle size analyzer, optical particle counter, resistance particle counter, and particle image analyzer.

Due to the advantages of wide particle size range, high speed, high precision, easy operation, and easy maintenance, laser particle size analyzer has gradually become the mainstream product in particle size testing. However, due to the diversity of particle testing requirements, particle market segmentation has emerged.

With the development of nanotechnology, nanoparticle testing has attracted more and more attention. Dynamic light scattering technology for nanoparticle testing has progressed by leaps and bounds. Photon-related technologies are also hot. Foreign manufacturers have developed dynamic light scattering laser particle size analyzers for molding products. Some manufacturers have successfully developed digital correlator technology based on FPGA technology, domestic dynamic light scattering nanometer particle size analyzer will also come out.

In addition, with the continuous improvement of people's requirements for product quality and the automation of industrial production processes, online particle testing technology will become the focus of competition in the particle industry, and domestic in this regard is still a blank.
