    1. Column Type – You must select either Datum or Condition. In the cases noted below, based on your Characterization selection at the top of the Characerization page, customized options may display for the following fields.
    2. Column Name and Column Property – Select or enter a column name.
      • If you selected Datum for Column Type (or if appropriate, Condition), the following characterizations display customized name fields. In some cases, based on your selection at the top of the characterization page, customized options may display for some fields.

        For a physico-chemical characterization, use the criteria in the first table.
        For an in vitro characterization, use the criterion in the second table.
        For an in vivo characterization, click [Other] to name the column yourself
