ROMIL is pleased to introduce PrimAg^® conductivity reference solutions for the calibration of conductivity meters, further extending the comprehensive PrimAg^® range of certified reference materials (CRMs).

Each calibrant or reference solution is supplied with a certificate of calibration detailing its calibrated or measured conductivity, as well as the associated uncertainty traced to ROMIL primary silver.

PrimAg^® is the clear choice when traceability is crucial. ROMIL is the only UK CRM manufacturer accredited to ISO 17025 requirements for calibration, and each PrimAg^®product is manufactured according to ISO Guide 34 and fully traceable to SI units, eliminating the need for any additional validation. The launch of the PrimAg^® range of conductivity reference solutions further extends this extensive product portfolio, perfectly complementing the existing broad selection of single and multi-element reference solutions, multi-ion solutions, pure stoichiometric substances and volumetric reagents, plus bespoke calibration mixes tailored to specific user requirements and instrumentation. 

For laboratories needing to meet the forthcoming USP <232>/<233> regulations for the determination of elemental impurities in pharmaceutical products and dietary supplements, PrimAg^® calibration mixes containing between six and 15 elements suitable for the calibration of inductively-coupled plasma methodologies are also available. Alternatively, laboratories can choose individually formulated reference solutions, custom-manufactured from high purity constituents characterised via the PrimAg^® traceability scheme to match specific analytes or required concentrations. For maximum flexibility, there is a choice of PrimAg^®-xtra, PrimAg^®-plus or PrimAg^®-lite – depending on the CRM – offering a range of certification levels to suit each laboratory’s specific applications.
