New image analysis particle size standards

Published: 6-Oct-2004


Whitehouse Scientific, which specialises in the field of particle size standards, has produced a new range of glass microsphere standards for calibrating image analysis methods of particle sizing.

The standards cover the range 50 to 5000 microns and are available in weights from 50 to 500 grams. They are calibrated by precision sieving methods and are traceable to international standards of length such as NIST and NPL. The standards have been developed to provide excellent resolution at the extremes of the size distribution, says the company. Particle sizing by image analysis is becoming increasingly popular, offering rapid analysis and providing unique information on shape.
