Description

SRM 99b - Soda Feldspar


This Standard Reference Material (SRM) is intended for use in the determination of constituent elements in feldspar or material of similar matrix.  SRM 99b is powdered soda feldspar that was sieved to less than 250 mesh (<60 μm) and blended to ensure homogeneity.  A unit of SRM 99b consists of one bottle containing approximately 40 grams of fine powder.
