Abstract
A method and apparatus to collect and store a sample of an environmental gas, e.g. air. A sample container or bottle is cooled below the condensation temperature of the environmental gas so that a partial vacuum is created in the container thus permitting environmental gas to be drawn into the bottle and condensed. Included in the apparatus are means to meter the quantity of environmental gas admitted to the bottle.
