Yttrium standard solution, NIST-3167A

This standard reference material is intended for use as a primary calibration standard for the quantitative determination of yttrium.

A unit consists of five 10 ml sealed borosilicate glass ampoules of an acidified aqueous solution prepared gravimetrically from high-purity yttrium (Ⅲ) oxide to contain a known mass fraction of yttrium.
