Abstract
A portable vessel for a sample of gas, some components of which may condence when cooled to ambient temperature. The container with inlet and outlet valves is surrounded by a heater and insulation so that the sampled material can be maintained above the dew point of any of its components. A method of use includes the step of purging the vessel with inert gas prior to the sample collection and introduction of the sample into an analyzer.
