The very narrow diameter standard deviations, makes them an excellent calibration material for applications requiring NIST traceability. The calculated concentration simplifies the dilution process and minimizes the need to make multiple adjustments during sample preparation.
Compared to the (Particle Size Standard) 3000 Series, the 3K series products are precisely diluted for immediate use in laser particle counters with minimal time-consuming adjustments of concentration.
These NIST traceable size standards therefore provide an accurate and convenient method for calibrating or checking the performance of particle counters widely used in cleanrooms and other contamination monitoring applications. They are supplied as suspensions of monodisperse polystyrene spheres (PSL) for use in airborne or liquid particle dispersion systems.
The suspensions contain only trace amounts of surfactant for low background interference.
