ROMIL launches PrimAg range of conductivity reference solutions
22 Nov 2017
ROMIL introduces PrimAg conductivity reference solutions for the calibration of conductivity meters, further extending the comprehensive 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.
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 range of conductivity reference solutions extends the company's extensive product portfolio, complementing the existing selection of single and multi-element reference solutions, multi-ion solutions, pure stoichiometric substances and volumetric reagents, as well as 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.
Laboratories can also choose individually formulated reference solutions, custom-manufactured from high purity constituents characterised via the PrimAg
traceability scheme to match specific analytes or required concentrations.
