POTS-1 Potato Starch Reference Material for Trace Metals and other Constituents

POTS-1 is a Reference Material prepared from food grade potato starch.

POTS-1 was prepared and characterized by the Centre for Land and Biological Resources Research, Agriculture Canada. The materials were transferred from the National Institute of Standards and Technology (NIST) to the National Research Council Canada (NRC). In 2014 NRC distributed samples of POTS-1 to several laboratories for elemental analysis. Reference values are weighted means of
results from at least two different analytical methods applied by analysts in different laboratories. The material was renamed POTS-1 by NRC.

This Reference Material (RM) is intended for use in evaluating analytical methods and instruments used for the determination of major, minor, and trace constituent elements in potato starch and other similar food, agricultural, and biological materials. A minimum sample mass of 500 mg is recommended.
