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 an ISO 17034 accredited Certificate of Calibration reporting its determined assay with associated uncertainty traced to ROMIL primary silver.
Also available are colour reference solutions for calibration of colorimeters and spectroscopic reference solutions for calibration of UV/Visible spectrophotometers and HPLC detectors.
