NIST Traceable Size Standards Particles
Calibrate and validate particle sizing and counting instruments Thermo Scientific™ NIST (National Institute of Standards and Technology) Traceable Size Standards work on an open platform without bias or restriction on any instrument brand or model. They come packaged in easy-to-use dropper-tipped bottles to minimize operator error by delivering the precise volume of beads into the instrument. Various polystyrene, silica, and glass beads are available in a broad range of sizes (20 nm to 2000 μm) to satisfy a broad range of instrument quality control and calibration needs.
Maximize instrument repeatability, reproducibility, and performance accuracy
Thermo Scientific™ Count Controls validate the results of laser particle counters regardless of brand to ensure they are accurately measuring for particulate matter in air, surface or liquid applications where contamination is a concern and requires diligent monitoring.
Count Controls
Applications
- Calibration of particle counters using laser scatter, light scatter, light blockage,
imaging microscopy, and electrical resistance. - Verify instrument QC by checking for instrument problems, shifts in laser
function, and calibration curve shape variations.
