Quality Assurance

1. We use international isotopic standards (NBS 19, LSVEC, OH1 to OH4, IAEA-600, IAEA-CH-6, IAEA N1, IAEA N2, etc.) to place all samples on the appropriate isotope scale (e.g., VSMOW, VPDB). Click here for an assortment of example reports.

* If your samples are poisoned (e.g., HgCl2), an additional charge of $20 will be applied to your bill for waste disposal.

Additional fees may be applied to your bill if the samples are not prepared correctly. If you are in doubt, please contact us (ankerssm@iastate.edu).

A 5% surcharge will be applied to any samples outside of ISU.
