  1. Sample Size and Type:  10 - 100 g of a representative whole seed or ground sample.  If ground, the particle sizes of samples should be sufficiently fine to resemble whole wheat flour (see "Sampling Grain for Deoxynivalenol (DON) Analysis: A Researchers Guide" on the USWBSI website).
  2. Packaging and Labeling:  Pack samples in coin envelopes and label them with sample numbers that correspond to the submitted datasheet.  The sample numbers should be consecutive.
  3. Datasheet:  An Excel spreadsheet includes sample numbers and PI´s information (see example - updated 8/6/15).  Please email datasheet to when submitting your samples and enclose a printed copy with your shipment.
