Certified Reference Materials

ROMIL’s (UK) PrimAg range of Certified Reference Materials (CRM’s) now have ISO Guide 34 Accreditation. This is in addition to ISO 17025 which they've held for the last ten years. The aim is that by extending Romil's accreditation status they offer a more comprehensive range of products to their customers.

This accreditation has been awarded by UKAS, who are world-renowned for being the most stringent board with their criteria for accreditation. Romil hope this gives confidence that in addition to being of the highest quality; PrimAg CRM’s are very carefully monitored and controlled.

What ISO Guide 34 means for the end-user is that no further validation of CRM’s is required. This is important as it results in ultimate ease of administration. ISO Guide 34 covers all the elements of ISO 17025 and some additional ones for production, storage and distribution.

Another point to make is although the PrimAg range is ISO Guide 34 accredited; Romil have not increased the prices. Romil have always aimed to provide a wide range of products at sensible prices and this is set to continue.

An additional benefit to customers is that Romil can now offer more accredited products. ISO Guide 34 is intended to be an assurance to the end user that the Reference Material Producer (RMP) is competent to manufacture their products to a certain standard. Therefore, once accreditation is granted the RMP can self certify their products without the need for further justification. So as always, if you do not see the product you need in Romil's literature, just ask as they are constantly looking at ways to expand their range.

The PrimAg range comprises single and multi-component solutions and pure stoichiometric substances. Romil also offer bespoke calibration mixes customised to user requirements and instrumentation.

PrimAg Reference Materials are offered with three different levels of certification depending on the analyst’s requirements. PrimAg-lite has no certificate and is offered as a low cost QC working reference material. The PrimAg-plus is supplied with a Certificate of Calibration detailing the nominal component with corresponding uncertainty. This certificate has the UKAS Guide 34 logo and is suitable for all ISO 17025 accredited Testing Laboratories. PrimAg-xtra is supplied with a Certificate of Calibration detailing the nominal component and also gives metallic impurities as determined by ICP-MS. The raw data is given with no correction made for interferences, allowing the user to make their own corrections according to the specific circumstances of their analysis.
