Description

This Standard Reference Material (SRM®) is intended primarily for the evaluation of methods for analysis of constituent elements in feldspar or material of similar matrix. NIST-70b is powdered potassium feldspar that was sieved to less than 75 µm (<200 mesh) and blended to ensure homogeneity. A unit of NIST-70b consists of one bottle containing approximately 40 grams of powder. /// Sample value(s) - please ask for current certificate.
