Water Isotope Analysis Systems

Water is life. By studying how it moves and carries other elements through the Earth’s ecosystems and by measuring its properties in various forms, scientists unlock important insights about the planet’s past, present, and future. Picarro Water Isotope Analysis Systems enable researchers to accurately measure δ¹⁸O, δ¹⁷O, δ²H, and ¹⁷O-excess in water quickly, simply, and without sample conversion. Their small, light, robust design makes them ideal for lab and field work. And, with a comprehensive selection of compatible peripherals, and ChemCorrect post-processing software, the Picarro systems can process just about any type of water sample.

Water Isotope analysis systems

One Design for Multiple Applications

The isotopic water analyzers are Picarro’s flagship products—and for good reason. They have established themselves as the “gold standard” in measurement technology in hydrology, ocean science, and paleoclimatology. Picarro Isotopic Water Analyzers have been deployed for a wide range of applications all over the world, including: to identify the influence of sea ice on ocean water vapor isotopes and Greenland ice core records; to reconstruct paleo temperatures through a triple isotope (δ2H, δ17O, δ18O) study on precipitation, drip water and speleothem fluid in a Central European cave; to map nutrient dynamics and residence time of the water in the Sacramento-San Joaquin River Delta.
