PrimAg® stoichiometric reference materials are high purity substances which may be used to calibrate routine working reagents of, for example, 'SA/AR/PA/ACS' quality, thereby establishing traceability to internationally agreed SI units. (See also PrimAg®-TvR ready to use traceable volumetric reagents).
Each substance reference material is accompanied by a Certificate of Calibration reporting its determined assay with associated uncertainty traced to ROMIL primary silver.
Also available is a set of reference solutions for absorbance calibration of UV/Visible spectrophotometers and HPLC detectors.
