Collection of dissolved gases from groundwater

摘要: A system for rapid collection of large volumes dissolved gases from groundwater pumps the water a large-diameter passage through small-diameter restrictor passage, and then into flow-through chamber. The causes drop in hydrostatic pressure traveling therein, causing spontaneous ebullition gas bubbles which are collected Testing reveals that proportion to their presence groundwater, thus allows accurate quantification concentrations groundwater. may beneficially be made easily portable, thereby allowing its use field as well laboratory settings.
