Follow water isotopes
through space and time.



Water isotope studies are a critical tool for understanding the global water cycle and addressing issues concerning water availability, quality and transport.

Picarro’s CRDS instruments make this type of research more accessible than ever before. Rather than dealing with the time, effort and uncertainties of transporting bottled samples to the lab, you can take our analyzers to remote locations and make measurements in the field, in real-time.

Locations, experiments and data will be more closely connected, making previously intractable scientific problems far more manageable.

Consider what it could do for your research.

  • Precipitation is isotopically labeled according to weather patterns associated with cloud formation and the specific location of rainfall. By mapping this isotopic distribution, it’s possible to track storms and understand climatic processes.
  • Monitor the movement of water through streams and rivers, underground aquifers, groundwater leaching or even within metabolic processes.

Research Applications

Groundwater quality

A group of researchers at the University of Vienna used a Picarro water isotope analyzer to measure the δD and δ18O of groundwater, as well as other parameters, to analyze the impact of groundwater on groundwater-fed gravel pit lakes (GPLs)

Water flow and circulation

The isotopic composition of depth-profiled water from several locations within Lake Geneva allows for tracing of Rhône River water.

Hydrogeochemical studies for sequestration

A research team from four academic institutions in China used a Picarro water isotope analyzer to measure groundwater recharge, flow pattern, age and mixing processes in saline aquifers. This research aids in the understanding of storage capacity and long-term security between hydrogeologic units when considering potential CO2 sequestration sites.
