The stable isotope lab at Duke (DEVIL)is seeking new clients who need analyses of biological or geological materials including solids, liquids and gases, for light stable isotopes of carbon, nitrogen, hydrogen and oxygen. We currently have very short turn-around time on samples analyzed by EA-CFIRMS, TCEA-CFIRMS or GasBench. As an incentive, we are offering a 20% discount from our regular fees for first-time clients.
