Picarro L1102-i CRDS

Picarro Isotope Water Analyzer

Model L1102-i CRDS (Cavity Ring-Down Spectroscopy) water analyzer with vaporization module V1102-i coupled to a CTC/Leaptec PAL autosampler (system installed 2010).

The system is based on near infrared laser light absorption in water vapor that allows for the precise measurement of 18O/16O and 2H/1H in the water molecules. This technique is referred to as isotope ratio infrared spectroscopy (IRIS) or laser absorption spectroscopy (LAS) in the recent literature.

Analytical capabilities: δ18O and δ2H in freshwater
