The Picarro L2140-i isotopic water analyzer enables simultaneous measurements of δ¹⁸O, δ¹⁷O, and δD, and determines¹⁷O-excess to sub 15 per meg (<0 .015‰) precision. scientists now have a simpler, less expensive option for high-precision measurements of water stable isotopes in liquids and vapor.

Measurements of¹⁷O-excess in conjunction with high precision measurements δ¹⁸O and δD enable geoscientists to enhance our understanding of present day climate and the interactions between the hydrosphere and biosphere, and to help reconstruct climates of the past. The ability

to quantify extremely small deviations in δ¹⁷O (i.e.,¹⁷O-excess), typically less than 0.1‰ in nature, is essential for paleoclimate, (eco) hydrology, and atmospheric science applications.
