Ion Chromatography (IC) Multi Element Cation Standard (5 Elements) in Water (H₂O) - Ca, K, Mg, Na, NH₄

The Ion Chromatography (IC) Multi Element Cation Standard (5 Elements) in H₂O is manufactured from ultra-pure salts. This product is manufactured gravimetrically. Prior to bottling; the final product is tested and verified using a state of the art ion chromatograph and is reported using the gravimetric result; corrected for density. The results are reported in mg/kg and mg/L on the basis of weight and density. The hold ISO 17025 accreditation (A2LA Ref: 6739.02) for calibration of laboratory balances.
- GHS/OSHA compliant, REACH
- This product is produced in a highly controlled cleanroom (ISO 7) environment; using ultra-pure water (specially treated for the production of ion chromatography standards) and triple leached pre-cleaned bottles. All of the uncertainties of measurement for the product are calculated according to Eurachem/CITAC guidelines and reported as expanded uncertainties at the 95% confidence level.
