Particle Count Control is a product containing National Institute of Standards and Technology (NIST) traceable size standards with a measured particle count.
The product was developed to provide process control data for particle counting consistency and verification of size calibration. The ready-to-use precision standard is designed for regular use in liquid particle counters. This documents the reproducibility of the particle counter by permitting a continuous record of its performance using a microsphere suspension with a known concentration.
The products are ideal for parenteral drug manufacturers seeking interim verification of USP <1788> “Particulate Matter in Injections”, Light Obscuration Particle Count Test.
