Pricing displayed is Nett. For order quantities above 4 units, ask your sales contact for a quotation. Reagecon's Osmium Standard for ICP; ICP-MS 100 µg/mL (100 ppm) in Water (H₂O) for ICP or ICP-MS is manufactured from ultra-pure metal (99.999%). This product is manufactured gravimetrically using the mass balance approach: 100% less the sum of all impurities (w/w). Prior to bottling; the final product is tested and verified using ICP-MS and is reported using the gravimetric result; corrected for density. To a specification of ± 0.2%. The results are reported in mg/kg and mg/L on the basis of weight and density. Reagecon 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 mass spectroscopy standards), triple distilled acids and triple leached pre-cleaned bottles. The titrimetry and spectroscopy are controlled and calibrated using separate standards, so the product comes with two layers of traceability including NIST Standards, where available. All of the uncertainties of measurement for this product are calculated according to Eurachem/CITAC guidelines and reported as expanded uncertainties at the 95% confidence level.Farbe und Form:LiquidOsmium Catalyst supported on Magnetite (0.07-0.09mmol/g)
