QC Standards
  • All of the following standards are prepared from high-purity metals or salts in sub-boiling distilled acids and packaged in 100, 250, and 500ml volumes.
  • The accuracy of all standards is certified to ± 0.5% of the stated concentrations against NIST SRM spectrometric standard solutions.
  • Each standard is accompanied by a Material Safety Data Sheet and Certificate of Analysis stating the NIST SRM used.
  • All standards are certified accurate for a period of one year from the date of shipment.
