Reference Materials and Calibration Services
The Reston Stable Isotope Laboratory (RSIL) of the United States Geological Survey provides isotopic reference materials and calibrates user-supplied materials. Reference materials are suitable for use in calibration of analytical instrumentation, for testing analytical methodologies, and for use as quality control samples.
Isotopic Reference Materials and Calibration Services
- To request Isotopic Reference Materials, a USGS Facility Service/User Agreement or Interagency Agreement (required for federal customers) needs to be filled out, signed, and transmitted to the RSIL. The signed agreement can either be scanned and saved as a pdf file and emailed to isotopes@usgs.gov or faxed to Jennifer Lorenz (secure fax number 703-648-5889). Generally, users only need to fill out this form for their first order. This form will be retained on file and can be used for subsequent orders for five years. After five years, the agreement will need to be renewed.
- Fill out the USGS RSIL Order Form and email it to isotopes@usgs.gov or fax it to Jennifer Lorenz (secure fax number 703-648-5889).
- After receiving the USGS Facility Service/User Agreement or Interagency Agreement and the USGS RSIL Order Form, an order confirmation will be sent to the customer, which is used by the customer to designate payment type. The accepted forms of payment per the USGS Facility Service/User Agreement are credit card, check and wire transfer. Federal customers are billed monthly per the terms of the Interagency Agreement. After payment information is received from the customer, both the payment and order are processed.
- Solid isotopic reference materials can be shipped immediately after the required documents have been received and the payment has been processed.
- The turnaround time for international distributed water references sealed in silver tubes is 1-3 weeks.
- If UPW (user-provided water) in silver tubes is required, the turnaround time is 1-2 weeks without calibration and 2-4 weeks with calibration. The user's samples should be sent to:
