NIST-Traceable PSL Spheres: Ensuring Size Calibration Accuracy in Laser Aerosol Spectrometers
In aerosol science and cleanroom monitoring, measurement precision is non-negotiable. Laser Aerosol Spectrometers (LAS) and Optical Particle Counters (OPC) rely heavily on accurate calibration to categorize particles by size. NIST-traceable Polystyrene Latex (PSL) spheres, ranging from 20nm to 900nm, serve as the industry gold standard for validating these instruments. These monodisperse particles provide a consistent, […]
