The analysis of the stable isotopes δ18O, δ17O and δD of the water molecule has established itself as an important tracer technology in diverse scientific disciplines: In hydrology, they help to quantify and qualify various components in the hydrological cycle such as groundwater recharge, solute inputs, surface and groundwater interaction, or evaporation processes. In ecohydrology, they are used to better understand water and matter cycles in plants and landscapes. For paleoclimatologists, stable oxygen isotopes in ice cores or sediment deposits on the seafloor provide "temperature proxies" and geochemical fingerprints to characterize climate events or ocean circulations of long ago. Water isotope analyzers are also in use on various research vessels by limnologists and oceanologists worldwide.
But not only science, also the food industry has discovered the stable isotopes for itself, for example for testing wine or fruit juices. The Picarro analyzers are particularly well suited to these diverse fields of application thanks to their CRDS laser technology, which is shielded from environmental influences, their low drift and their field suitability, as well as a wide range of peripheral devices.
