LGC adds Whitehouse Scientific's particle standards

LGC Standards has added particle size standards from Whitehouse Scientific to its extensive range of physical Reference Materials.

LGC Standards has added particle size standards from Whitehouse Scientific to its extensive range of physical Reference Materials.

The standards include high quality particle size standards ranging from millimetre to micron diameters and are featured in LGC's new 2008 catalogue for Physical Standards.

The products complement the comprehensive range of reference standards for measuring physical characteristics. Thermal, surface and optical properties, particle shape and size, ion activity, viscosity, electrical, and polymeric properties are included as well as old favourites such as melting point standards and standards for use with differential scanning calorimetry (DSC).

LGC Standards director Dr Matthias Brommer expressed delight at new of LGC's extended portfolio offering.

"Laboratories across the world rely on our extensive range and technical expertise to help them source the right material, whether they are in the pharmaceutical of food sector, industrial or environmental. Many of them rely on accurate measurement of particle size, and no products meet higher specifications than Whitehouse Scientific's".

Whitehouse Scientific has been producing precision glass microspheres for calibrating all types of particle size instruments for 25 years.

According to Dr Graham Rideal, managing director of Whitehouse Scientific, the company is the highest-ranking European certification laboratory for primary methods of particle size analysis.

He said: "Having filled over one million bottles using a unique 100 stage spinning riffler system, we are now the world's leading manufacturer of single-shot glass microsphere standards."

The reference products are nearly all NIST traceable and range in size from 0.1µm to 5 mm and are available as single sizes or broad distribution standards. In addition to calibration, applications include filter testing, space research, nuclear fall-out studies, micro-engineering and precision spacers.
