Analytical Standards

Analytical Inorganic Standards


Features our quality standards, with product listings subdivided into the following categories:

Ion Standard Solutions

  • ICP/DCP Standards
    • Element concentration is 10,000 µg/mL; exact value is stated on the label
    • Trace impurities are below 20 µg/mL
    • Prepared from the highest quality solvents and solutes (99.999+% pure)
    • Rigorously assayed: certificate of analysis includes matrix concentration, named element concentration, and any impurities which have been detected

  • Atomic Absorption Standards
