The SIPERG Stable Isotope Laboratory is intended to be a hands-on teaching and research facility. The laboratory is devoted to performing continuous-flow isotopic (‰) and elemental (%) analyses of carbon (C), nitrogen (N), oxygen (O) and hydrogen (H) in organic and inorganic substrates (solids, liquids, and gases). The lab supports research in different disciplines, including oceanography, paleoclimatology, geology, ecology, agronomy, and chemistry. In addition, analyses of samples for other interested researchers are also performed in the lab.

Price varies for solid samples run on the Thermochemical Elemental Analyzer (TC/EA).
If you want to weigh and wrap your own samples, you can purchase the tin capsules and trays as a kit from EA Consumables (https://eaconsumables.com/cell-well-96-pos-flat-bottom-with-lid.html). The above rates apply to private researchers and universities. Corporate rates available upon request. Additional fees may be applied to your bill if the samples are not prepared correctly. If you are in doubt, please contact us. If your samples are poisoned (e.g., HgCl2), an additional charge of $20 will be applied to your bill for waste disposal.
*Soils must be acid treated, pulverized, and dried by researcher to remove inorganic carbon.
"Prompt response, high quality and reliable work,"
"Fast and efficient"
"The service was excellent. I use their 18O stable isotope analysis twice and the results were fast and accurate. The person in charge will contact us immediately when they receive my samples and tell us if there is any problem about our samples. Any question from us will respond immediately. I will continue to use their service."
