Submission Forms

Please use these forms every time you submit samples for analysis.

96 well sample tray form - print this out, fill it in by hand, and send it in along with each sample tray (optional).

DEVIL submission form - use this for all isotope analyses. Download this Excel spreadsheet, enter information about each sample, and e-mail to jkarr@duke.edu. Printing a hard copy of the form is not necessary. Note that for isotope analysis the target size for N is ~3-12 µmol and for C is ~10-200 µmol. Maximum sample weight is 100 mg. Samples should be no larger than needed to meet the minimum µmol requirements for both N and C.

CN submission form - use this for %C, %N only. Download this Excel spreadsheet, enter information about each sample, and e-mail to cwcook@duke.edu. Sample weight requirements are not as exacting as for isotope analysis, but please ask if in doubt. Typical target weights range from 2-10 mg for leaves and seeds to 50-100 mg for soil.
