The Bureau of Analysed Samples Ltd. (BAS) has been producing Certified Reference Materials for nearly eighty years. A large range of CRMs have been developed and maintained over this period, all under the auspices of an Honorary Advisory Committee and a body of approximately 150 Co-operating Analysts representing both Independent Laboratories and Manufacturers and Users of the materials concerned.
In November 1994, the Quality System of the Bureau of Analysed Samples Ltd. was formally approved and recognised by the award of a Certificate of Registration to the Quality Standard BS EN ISO 9002:1994 for the production and supply of CRMs, RMs and SUS. This certificate has now been re-validated to the new Standard BS EN ISO 9001:2008. Furthermore, BAS was accredited, in June 2006, to the International Guide, ISO Guide 34:2000 and the accreditation has since been updated to the current version, ISO Guide 34:2009.
Over the years our website has undergone many improvements and now includes a database of our current range of CRMs, together with the more popular OSRM materials. This is simultaneously searchable for up to six constituents. Products and their corresponding Certificates are now also searchable by name.
We have continued the exercise to update BAS certificates to provide more comprehensive statistical information, including standard deviation and half-width confidence intervals where these did not previously exist. Please check the Numerical Index on pages 25-28 of the BAS Catalogue to ensure that you have the latest certificate. If you have not, then please check this website for our selection of current certificates. If you are unable to locate a current certificate then we will gladly supply it on request.
Our OSRM catalogue provides details of CRMs and RMs, prepared by 28 reputable producers, and many of these are retained in our stock at Newham Hall for prompt despatch, and those which are not immediately available from our stock are usually obtainable from the Producer concerned within two weeks.
If CRMs and RMs of specifications not covered in our BAS and OSRM Catalogues are sought, we are very happy to search for any such sample which may be known to us through our personal worldwide database.
BAS remains as one of the few Producers of CRMs and RMs to have gained Accreditation to ISO Guide 34:2000, and we strive to continually provide the quality of products and service for which the award was gained.
