World’s first and only true 20 nm chemical particle counter
Leading-edge microelectronic processes require very clean process chemicals that are highly filtered and regulated to a particle size of 20 nm or below. With 20 nm particle sensitivity, the Chem 20 Chemical Particle Counter from Particle Measuring Systems (PMS)is the world’s most sensitive particle sensor for high purity process chemicals and latest edition to our full line of liquid particle counters.

Extensive data on chemical distribution and packaging systems proves that the Chem 20 chemical particle counter, with 20 nm sensitivity, detects larger concentrations of particles with better statistics than competitive products. The Chem 20 Chemical Particle Counter is a valuable tool that enables facility and process engineers to quickly detect and characterize chemical particle sources before they impact process and device performance.

The Chem 20 is one of Particle Measuring Systems’ “Industry Leading Sensitivity” products. This means that there are no products on the market that are more sensitive than these and only PMS offers a line of products covering this many elements of production monitoring. PMS currently leads the market in monitoring performance, sensitivity and reliability in the Ultrapure Water, Chemical and Airborne Molecular Contamination Monitoring fields. PMS’ superior knowledge, technology and service provides High Tech and Chemical manufacturing companies the most advanced tools to make accurate data-driven decisions, improving both performance and yield.
