ABSTRACT:
An apparatus for releasing gaseous material into the atmosphere employs a sorbent material that is sorptively saturated with a predetermined quantity of the gaseous material at a predetermined pressure, preferably approximately equal to atmospheric pressure. The gaseous material to be released preferably has a vapor pressure lower than the predetermined pressure at which the sorbent material is sorptively saturated. The apparatus also includes capability of selectively exposing the sorbent material to the atmosphere in order to allow the gaseous material to be desorptively released.
