ABSTRACT:
A surfactant mediation sparge tube for use with analytical instruments includes a two part purge vessel having an upper portion attached to a lower portion by a coupling device, an inner foam directing tube carried by a non-permeable disk positioned generally between the purge vessel upper and lower portions, and an internal physical foam barrier positioned in the purge vessel upper portion. The foam directing tube and disk, which may be fixed or removable, seals the lower portion of the vessel from the upper portion, directing purge gas and foam to the upper portion of the vessel only via the inner foam directing tube.
