To submit samples, please contact Idaho Stable Isotopes Laboratory to make scheduling arrangements and receive instructions. For certain solid materials, special considerations must be made prior to weighing in order to select the appropriate amount. If you do choose to pack your own for the EA or TC/EA, please use a 96-well cell plate and record sample ID and weights (3-decimal places in mg). Also, for all submissions, please complete the ISIL Sample Submission form and email it to mward@uidaho.edu.
