The SGT is proud to offer the following CRMs prepared in collaboration with the Bureau of Analysed Samples Ltd

SGT Dolomite (BCS-CRM 512) SGT Limestone (BCS-CRM 513)

SGT Feldspar (BCS-CRM 376/1)  SGT Soda-Ash (BCS-CRM 526)


Please note that this Potash Feldspar has been produced under ISO Guide 34 accreditation.

These materials are available in bottles of 100g of finely divided material for chemical analysis passing a nominal 250 micron aperture. The cost is £70.00 plus postage to non members and at the discounted rate of £50.00 plus postage for SGT members.

The CRMs will remain stable provided that the bottle remains sealed and is stored in a dry atmosphere. When the bottle has been opened the lid should be secured immediately after use. In order to ensure that a fully representative sample is taken, users should take a minimum sub-sample size of 1.0 g. Users of this material should be aware that the use of a smaller sub-sample size will invalidate the certified values and the associated 95% confidence limits. Provided that the material is stored in a suitable environment there will be no contribution to the uncertainty from the long term stability of this CRM.
