Liquid Water Laser (CRDS) 

δ2H and δ18O of Water

A Picarro L2130-I Cavity Ring Down Spectrometer is used to measure the δ18O and δ2H ratios of liquid water. The instrumentation uses an autosampler coupled to a CRDS analyzer.  One µl of water is injected into a heated vaporization chamber.  After vaporization the water is allows to flow into a laser cavity for analysis.

Typical sample size:    1-2 μl
