Picarro’s most popular isotopic water analyzer for δ18O and δD, in the lab or in the field.

Testing beverages for region of origin
• Measuring the oxygen and hydrogen stable isotope ratios of the water in beverages can yield information regarding their point of origin.
• E.g. juice

WS-CRDS instruments now provide simple access to stable isotope ratios for the three life elements (C, H, O). Once the growing, harvesting and/or processing of natural products is complete, these ratios leave a permanent and characteristic signature that can be easily read and used to screen these products, e.g. to tell whether a wine is from South America or France, or to confirm whether orange juice is from Brazil or Florida.
