PROTOCOL FOR SUBMITTING SAMPLES:

 

  1. Sample Size and Type:  10 - 100 g of a representative whole seed or ground sample.  If ground, the particle size 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 (A size of #5.5 envelope is preferred, i.e., 3 1/8” x 5 1/2”) and label them with sample numbers that correspond to the submitted datasheet.  The sample numbers should be consecutive.  You should secure sample envelopes with rubber bands (see example 1).
  3. Datasheet:  An Excel spreadsheet includes sample numbers and PI´s information (see example 2).  Please email datasheet to dongx001@umn.edu when submitting your samples and enclose a printed copy with your shipment.
  4. Ship to:
    Attn: Yanhong Dong
    Room P106 Stakman Hall 1519 Gortner Ave University of Minnesota St. Paul, MN 55108 PH:  612-625-2751

Date considerations:  We take samples year round, but data turn around time depends on time of year and how many samples are already submitted.
