Picarro L2140-i δ18O, δ17O, δD isotope analyser

These water isotope analysers provide simultaneous measurement of δ¹⁸O, δ¹⁷O, δD in liquids and vapor. Currently, 2 such analysers are available at FARLAB. The system is able to provide high precision measurements in the laboratory and in the field, for example when deployed on a ship for seawater isotope results in near real time during scientific expeditions. Standard analysis provides δ¹⁸O, δD and Deuterium excess at permil precision, specialized analysis also includes δ¹⁷O for ¹⁷O-excess at per-meg precision. For liquid sample measurements we use an autosampler, for vapour measurements a Picarro Standards Delivery Module is available allowing calibration with two working standards. The sampling strategy can be optimized to achieve the best possible results in process studies of water mass mixing, sea-ice, and identification of fresh water sources from samples of snow, ice, ground waters, precipitation, etc. Contact us about the possibility to deploy this instrument on an upcoming expedition, or to analyse your samples.
