Ecohydrology Laboratory

Lab Services

The Ecohydrology Lab offers stable isotope analysis of 2H and 18O using the PICARRO L2120-i. The PICARRO L2120-i provides simultaneous, high precision 2H and 18O measurements.  Dr. Holly Barnard oversees the instrument and its operations.  We use Picarro's ChemCorrect™ software to identify and quantify organic contamination in extracted plant and soil samples.  In the future, we plan to add a microcombustion module for samples with high organic content.

Contact Dr. Barnard (holly.barnard@colorado.edu) prior to mailing and submitting samples.  All samples are required to be filtered prior to analysis to maintain instrument performance.  If filtering is problem due to small sample size, we can discuss.  The Ecohydrology lab is not responsible for samples that are broken in the mail during shipping to the lab.  CU-Boulder students with a small number of pilot project samples should contact Dr. Barnard about student discounts.  Below is our current price structure:
