The primary analyses performed in our lab are listed below. If you request additional services or special procedures please consult with the lab manager. It is the responsibility of the researcher to arrange sample preparation that coincides with research and laboratory requirements. Please contact the laboratory manager before submitting samples to determine requirements and costs specific to your project (

The prices below are for all external clients. We have two reduced rate structures for WSU clients. Clients from the College of Arts and Sciences at WSU receive the lowest rate. If your funding source will come from within WSU, click here to view internal rates.

As a courtesy to new clients and to aid in project development, we will analyze a small subset of prepped samples for no charge. Contact the laboratory manager for details.

*Cost of dual CN analysis assumes both elements can be targeted from the same sample. Samples with C:N 6:1< or > 60:1 may require C and N to be targeted from two separate analyses for optimum results.

Replicate analyses are treated as an independent sample unless there was an error on our part.
