Samples should be submitted to the tray marked "Samples In", located in the cabinet just outside of Caudill 040. All samples must be accompanied by an online submission form (TO BE POSTED 01/23/15).

The more information provided about an analyte, the higher quality the results will be. Important information includes, but is not limited to:

  • Empirical Formula
  • Molecular Weight
  • Molecular Structure
  • Primary Sequence (for peptides and proteins)
  • Concentration
  • Conditions under which degradation can occur
  • Presence of buffers and salts

Please contact the lab Director for training, if you are interested in becoming an open access user.
