Water - δD, δ18O


We employ two Picarro liquid water laser analyzers dedicated to measuring δD and δ18O of water. We are tied to the VSMOW international scale via VSMOW and SLAP for our water isotope measurements. We maintain a suite of in-house reference waters measured against VSMOW and SLAP using GISP as a quality standard.
