IBR Laboratories — Partnership | 1 November 2011

IBR Laboratories LogoFilter Integrity Limited is proud to announce that it has entered into a partnership with IBR Laboratories of Grass Lake Michigan USA to promote and develop filter testing and performance validation capabilities.

Andrew Chalmers, Director at Filter Integrity Limited commented:

I'm personally delighted to have agreed a partnership with IBR Laboratories. I've worked with Susan and her team over the past 20 years, bringing an independent and certified validation to performance claims for in-house developed filtration products. The development of the testing facility in Milton Keynes now brings a new facility to Europe, extending the capability already available at the Grass Lake facility in the USA.

This partnership is a further important step for Filter Integrity Limited as we develop our support capabilities in our target market of filter testing and validation. An exciting time.

Susan Goldsmith, Managing Director at IBR Laboratories added:

IBR is very pleased to add Filter Integrity as a partner in our air filter testing services. FIL brings a powerful combination of technical strength, commitment to consensus standards work, and service to the industry. Our twenty years of technical association is the basis for a now expanded business partnership.

The Filter Integrity Limited website will be updated to reflect this new development during November. We will also be attending Filtration 2011 in Chicago with IBR Laboratories if you would like to meet us on the stand there. Look out for the new information updates.

NEW MFP ULPA Nano Filter Media Test Stand extends test range down to 5nm | 28 May 2011

Following the launch of the new Nano instruments at FILTECH 2011 the natural development of the MFP range of filter media testing stands has followed.

MFP ULPA Nano takes the well established MFP automation and control and adds:

  • the new Differential Electrical Mobility Classifier or DEMC allowing the generation of stream of mono-disperse particles in the 3 - 800 nm range from a poly-disperse generator mounted on the test stand.
  • the novel UF-CPC an instrument which can count particle in the size range of 3 - 800 nm.

The MFP ULPA Nano allows standardised testing of filter medias in accordance with standards such as EN 1822-3 and the identification of MPPS in the nano range. Combined with the other MFP systems in the available range efficiencies of filter media can be tested from 5nm to 100um.

The addition of this new instrument extends the MFP range capabilities further into the nano region. The MFP range has already been accepted by leading filter media manufacturers and research institutions as a robust, accurate and user freindly system with over 100 MFP systems in use around the world. The ULPA Nano is a novel solution allowing increasingly efficient medias with MPPS in the nano region to be better assessed.

NEW Nano Instrumentation Launched at FILTECH 2011 | 22 March 2011

FILTECH 2011 is selected as an appropriate venue for the launch of an extension to the Palas range of Nano instrumentation. Palas GmbH are a prime sponsor for the event, which is hosted by the lovely city of Wiesbaden, Germany.

The new Differential Electrical Mobility Classifier or DEMC is based around an already well proven design and allows the precision separation of a stream of mono-disperse particles in the 3 - 1200 nm range, from a poly-disperse sample.

When this is combined with the novel UF-CPC already in the Palas range, a new instrument, the U-SMPS or Universal Scanning Mobility Particle Sizer is the result, an instrument which can measure and define an aerosol particle size distribution in the range of 3 - 1200 nm.

Of interest to current users of CPC's, if that the DEMC can also be configured for use with a range of existing CPC's, to update instrumentation to operate as an SMPS.

The addition of these new instruments brings us full capability for aerosol scientists operating in the sub-micron regions and will be of interest to both new customers and those already familiar with Palas Aerosol Science equipment.

PALAS GmbH — UK Sales Partnership | 5 November 2010

Filter Integrity Limited is proud to announce that it has been selected by PALAS GmbH of Karlsruhe Germany to be a UK Sales Partner.

Andrew Chalmers, Director at Filter Integrity Limited commented:

I'm personally delighted to have agreed this sales partnership with PALAS GmbH. It was some 20 years ago when I worked with one of the first instruments based on the 90° scattered white light principle‚ referenced the HC15‚ which was one of the first capable of aerosol spectrometry at line pressures of 7 barg. Over the intervening years the performance and design has been improved several fold by the PALAS® development team‚ most recently demonstrated in the release of the new welas® Digital range.

PALAS are both an innovative and quality focused company with a diverse range of instruments and particle generation technologies and a strong customer service culture. New developments are impressive‚ both of stand alone equipment and custom engineered systems to meet a user specification. Filter Integrity Limited is looking forward to further expanding the presence of their instruments and technologies in the UK.

This is an important step for Filter Integrity Limited as we develop our support capabilities in our target market of filter testing and validation, but also in expanding our influence into other areas of aerosol science. An exciting time.

The Filter Integrity Limited website will be updated to reflect this new development during November. Look out for the new information updates.
