Sample preparation

Always perform moisture and protein testing on clean grain. Contaminated samples can skew results and reduce the lifespan of your testing equipment.

      1. Collect a representative sample of the lot of grain you are testing.

        Proper sample collection is crucial for accurate testing and grading results. Refer to the Canadian Grain Commission (CGC) website for instructions on how to take a representative sample.

      2. Reduce the sample volume using an approved Boerner-type divider or the three-bucket method.

        Perten moisture meters and protein analyzers require 700 grams of clean grain, while the volume of grain for 919 moisture meters is specific to each commodity.

        Refer to the CGC website for information about reducing composite grain samples.

      3. Clean the reduced sample.

        Follow the instructions available in the CGC’s Official Grain Grading Guide.
