ROMIL PrimAg® Reference Materials

traceable to SI Units via ultrapure primary reference silver

ROMIL Ltd is an ISO Guide 34 accredited producer of Certified Reference Materials (CRMs). Our extensive PrimAg® range comprises single and multi-component element and ion solutions, pure stoichiometric substances and volumetric reagents. We also offer bespoke calibration mixes customised to user requirements and instrumentation.

Under ISO 17025, testing laboratories should demonstrate their confidence in the stability, homogeneity and storage of their CRMs. A key feature of ISO Guide 34 is that these criteria are built into the scheme. Thus, PrimAg® CRMs need no further validation.
