Inorganic Reference Materials

High-quality Inorganic Reference Materials 

We offer a full range of inorganic standards for IC, AA, ICP, and ICP-MS. The highly characterized standards in our Assurance and Claritas PPT lines are intended for ICP and ICP-MS trace analysis. We have built our reputation by providing chemists and environmental scientists products that exhibit quality, reliability, and convenience.

Inorganic Standards Can Be Used For:

  • Atomic Absorption (AA)
  • Inductively Coupled Plasma (ICP)
  • Inductively Coupled Plasma-Mass Spectrometry (ICP-MS)
  • Ion Chromatography (IC)

Features of Spex Inorganic Standards:
