The Deep Water Gas Analyzer combines membrane separation technology with Los Gatos Research’s cavity enhanced laser absorption spectroscopy technology to provide in situ measurements of methane and carbon dioxide at depths to 2500 meters. Designed for applications such as ocean acidification, carbon sequestration, methane hydrate and hydrothermal vent studies, these novel analyzers provide real-time measurements of dissolved gases in oceans and lakes.
