ISO 21501: A Standard Methodology to Optical Particle Counter Calibration and What It Means to Cleanroom Owners
by Hach Ultra
ISO 21501 is a new family of standards describing the instruments and calibration requirements for determining particle size distribution using light interaction methods. It represents the culmination of work by instrumentation manufacturers and industry users and comes at a critical time for the life science industry with the increasing trend for real-time air particle monitoring in cleanrooms using light scattering air particle counters.
