Filter efficiency test has NIST
traceability
Whitehouse Scientific will introduce a new filter efficiency test at Filtech 2007 (27 Feb - 1 Mar 2007; Wiesbaden, Germany).
Whitehouse Scientific will introduce a new filter efficiency test at Filtech 2007 (27 Feb - 1 Mar 2007; Wiesbaden, Germany) Using fine silica glass beads of 1.5, 2, 3, 4.5, 5 and 6 um diameter, the new test enables measurement down to very fine pore sizes

On-site calibration of test sieves simplified
The on-site calibration of test sieves has been simplified by the introduction of new software from Whitehouse Scientific.
The Whitehouse approach allows full NIST traceability, something that in the past has presented a challenge for users of fine pore size filters.
To perform the test, standards are made into a dilute aqueous suspension which is drawn through the filter medium using a simple vacuum system.
Efficiency is measured by determining the percentage of standard retained in the filter.
Dr Graham Rideal, managing director of Whitehouse Scientific and former chairman of the Filtration Society, will also present a conference paper on 28 February, entitled: Challenge testing by precision glass microspheres - a new physical method of measuring pore sizes.
He and other members of the Whitehouse team will be available on the company's exhibition stand to discuss individual filter testing requirements. Request a free brochure from Whitehouse Scientific ...
