29-Feb-2008 - LGC Standards measures up to size with Whitehouse
Scientific
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
Particle size is a crucial element in the behaviour and
consistency of a range of products. It is important in the
production of foods such as spices, cereals and sugars -ensuring
your favourite cocoa powder is the right consistency to mix
correctly and has the right feel on drinking relies on particle
size. From grading fragments for grinding diamond to preparing the
appropriate particle size of the active ingredient in a
pharmaceutical, getting the size right is a requirement for many
processes and laboratories across many sectors need to be confident
of its measurement.
LGC Standards includes the Whitehouse Scientific particle size
series in a 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).
Dr Matthias Brommer, Director of LGC Standards, said: "I am
delighted we are able to offer such a prestigious range to our
customers. As the leading reference materials supplier in Europe,
LGC Standards provides a portfolio of standard and matrix reference
materials for laboratories in a broad range of sectors.
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."
Dr Graham Rideal, Managing Director of Whitehouse Scientific,
agrees: "Whitehouse Scientific has been producing precision
glass microspheres for calibration for 25 years and is the highest
ranking European certification laboratory for primary methods of
particle size analysis. 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.
