Sample Requirements
All samples should be packaged individually and labeled with a numeric code. Supply us with expected elemental concentration and isotopic enrichment (e.g., % N and atom% 15N). Provide contact and billing information.
- Solid samples - should be dried and ground to pass a 40-mesh screen or better (powdered)
- Solution samples - should first be dried or diffused onto filter paper disks
- Gas samples - please contact us for information on preparation of gas samples
- FAME or other GC-IRMS samples - please contact us for details
Total price and turn around time vary. Please contact David Myrold with any questions about price or sample requirements.
