SRM 1568a - Rice Flour

This Standard Reference Material (SRM) is intended primarily for calibrating instruments and evaluating the reliability of  analytical  methods for the determination  of minor and trace elements in rice flour and similar  agricultural food products. The rice flour for this SRM was described  by the supplier  as 100  % long grain  from Arkansas.   At NIST, the material was passed through a 425 -tm (No.  40) sieve and
blended.   The bottled material was then radiation sterilized at Neutron Products,  Inc., 
Dickerson,  MD.
