一般說明

Arsenic(III) oxide is a volumetric standard produced under rigorous conditions and measured with the highest possible precision. Its content determination and homogeneity assessment are carried out using volumetric redox titration as the primary analysis method.

應用

The reference material is to be used as a reductometric standard for titer determinations in redox titrations.

特點和優勢

  • Available as a solid in a secure glass bottle to ensure its stability for the entire shelf life until opened.
  • Traceable to NIST standard reference material
  • Offers accurate titer determinations
  • Accompanied by a certificate of analysis (CoA)
