Below are the current prices for analyses at the STRI Biogeochemistry Lab. Analysis performed by investigator means that the researcher manages their own sample prep and analysis at STRI, with limited assistance from STRI staff. These costs cover supplies needed for the analysis, such as reagents and vials. These individuals must be registered as STRI visitors to use the lab space. Analyses performed by the BGC lab staff include any samples that we receive where the project investigator is not present in the lab. Please contact the BGC lab for price estimates not shown here and for any questions concerning prices and analysis.
