McDonnell Extraction & Stable Isotope Lab
The McDonnell Extraction & Stable Isotope Lab is equipped with several Los Gatos Research (LGR) liquid and vapor water Off-Axis Integrated-Cavity Output Spectroscopy (Off-Axis ICOS) machines for the analysis of stable isotopes found in water. The lab can measure the ratios of D/H, 18O/16O and 17O/16O isotopes of fresh water and soil water samples. The McDonnell Extraction & Stable Isotope Lab is equipped with several methods for extracting fresh water from soil and plant material (Centrifugation, High-Pressure Mechanical Squeezing & Cryogenic Vacuum Extraction). The extracted water is suitable for further analyses such as D/H, 18O/16O and 17O/16O isotopes of fresh water.
