Sodium Standard for Flame Photometry 10,000ppm

The Sodium Standard for Flame Photometry (10;000ppm) in H₂O is manufactured from ultra-pure salt. This product is manufactured gravimetrically. Prior to bottling; the final product is tested and verified using ICP-MS and is reported using the gravimetric result; to a specification of ± 0.2%. The results are reported in mg/L on the basis of weight. The hold ISO 17025 (A2LA Ref: 6739.02) accreditation 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). 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.
