The CRA Carbohydrate Check Sample Program (CCSP) is designed for the corn refining industry and users of refined corn products. It allows laboratories testing corn wet-milled products to compare the precision of their testing methods with the performance of other labs doing the same types of analysis. Validation through a check sample program offers an important tool in maintaining analytical accuracy.
