Analytical Services and Prices (FY 2012)

Revised prices go into effect April 1, 2013.


Analytical Services

  • The submitter should fill out either the Standard Submission Excel Form or the QWDATA Compatible Submission Excel Form (an individual file is needed for each type of analysis). The file should be either e-mailed to isotopes@usgs.gov (preferred) or saved to a 3.5" diskette or a CD and submitted with samples. Submitters should not change the format of a Submission Excel file because laboratory personnel may not be able to import it without modifying it. Modifying the format of Submission Excel files may result in an additional charge for time needed to correct the formatting.
    If users provide information on the QWDATA Compatible Submission Excel Form, the QWDATA files, Sample_d.dat and Result_d.dat, will be uploaded on the QW Data Transfer System (QWDX) with USGS procedure codes (List of RSIL lab codes, method codes, an procedure codes) and an Excel spreadsheet of the results and confirmation of successful upload to QWDX system will be e-mailed to the sample submitter.
  • Advance Request for Analytical Services Form. Request and pay in advance for isotopic analyses of samples to be collected next fiscal year.
  • Submissions should be sent to:
    USGS--Isotope Laboratory
    431 National Center
    12201 Sunrise Valley Dr
    Reston, VA 20192
    (703) 648-5859
  • If you ship your samples in a cooler and want your cooler returned, please provide your FedEx account number, otherwise a cooler return fee will be added to your standard voucher.
  • General turnaround time for analysis is 2-4 weeks, but may be longer due to seasonal sample load. For information on express services, please email isotopes@usgs.gov. Priority service is available with advance notice. Turn-around time for priority service is 24 to 48 hours for hydrogen and oxygen isotope ratios of water. The surcharge is an additional 50 percent. Please contact the laboratory to arrange.
  • Laboratory services are provided for USGS programs and personnel. However, laboratory services can be provided to other federal, state, and county agencies, but these analytical costs will be higher than those listed because other costs, such as USGS overhead, must be added. Please contact the Reston Stable Isotope Laboratory for prices.
