Manufacturer and model:
Picarro L2140i Cavity Ring-Down Spectroscopy for water isotope and a Standards
Delivery Module for measuring vapor.

General Information:
The Picarro L2140i measures the isotopic composition (δ 2 H, δ 18 O and δ 17 O) of water and
vapor and can be used for a variety of applications in earth sciences, environmental
sciences, chemistry and biology.

Key Features:
The Picarro L2140i measures the isotopic composition of tiny amounts (~5 ul) of water
and vapor. In our lab, we developed a method that achieves very high precision (0.03‰,
0.2‰, and 5 permeg for δ 2 H, δ 18 O and 17 O-excess, respectively).
