The Basics of Liquid Particle Counters: How Particles are Counted

Liquid particle counting is used to measure the size and distribution of particles in a liquid sample. The particle distribution and size are measured by irradiating a liquid sample with a laser diode and detecting the scattered light. The properties of the scattered light are related to the magnitude of the particle size. Liquid particle counters may be used for batch sampling or online (continuous monitoring) applications like water treatment plants or used in Pharmaceutical sterile water for injectable (WFI) monitoring.
