Ezy-Cal™

1.00

This product line offers a series of ready-to-use standards for validating optical particle counters with no dilution and handling. The products are suspensions of monodisperse polymer microspheres in water with a concentration of 2000 particles per mL. A magnetic stir bar is included in each bottle for clean, convenient and direct sampling by instruments.
This series of size standards is provided for setting or checking the calibration of channel thresholds or for checking the count precision of liquid-borne particle counters. Their certified diameters are traceable to NIST. They are packaged as 100mL screw-cap bottles, sufficient for four or five calibration procedures on most counters.
The microspheres are composed of polystyrene, which has an index of refraction of 1.59 @ 589nm and a density of 1.05 g/cm3. The aqueous suspension medium contains a combination of dispersing agents, which help to keep the particles from clumping or sticking to flow surfaces in the particle counter.
The EZY-CAL™ product line meets all of the unique and demanding requirements of the contamination control laboratory in modern industries.

Description

Particle Count Controls are suspensions of (NIST traceable) particles with closely defined counts per ml. They can be used for the monitoring of liquid particle counters in contamination control applications, for instance in semiconductor cleanrooms.
Part of this product line are the 3K4K series, the Pharm-Trol™, Ezy-Cal™ and Count-Cal™ series by Thermo Scientific; and the PharmaCount™ series by Applied Microspheres. These particle count controls are designed to facilitate the control of liquid particle counters in pharmaceutical QC laboratories that need to comply with US, European, Japanese or Korean Pharmacopeia regulations. Part of the PharmaCount™ series is a set of instrument specific controls for the easy calibration of Accusizer instruments, which are commonly used in this environment.

Single Particle Optical Sizing Instruments using this principle for particle sizing and counting look at the cross section/shadow of the individual particles. Liquid borne particle samples are analyzed using a photodetector and laser diode. As the particles pass singly between the photodetector and laser diode, there is a voltage drop that can be correlated to a standard calibration curve. This method is normally used for particle counting methods in the 2-100µm size range. The 3K4K series Particle Counter Size Standards are ideally suited for the calibration or validation of these instruments They are diluted to optimal concentrations for direct use, minimizing time consuming concentration adjustments.
