A scrubber for removing pollutants from a gas comprising a housing for conducting the gas therethrough, a mechanism for introducing pollutant-reactive filtering agent into the housing, a sump for collecting the filtering agent and having a first volume, and an intermediate sump for collecting the filtering agent and channeling the filtering agent into the sump, the intermediate sump having a second volume that is less than the first volume.

Scrubber and method for removing pollutants from a gas with intermediate sump for collecting filtering agent

Apparatus for generating calibration gas comprising a contained stream of carrier gas, and a chamber containing at least part of the stream and a volatile reference liquid held by a wick structure so that as the stream passes through the chamber, the volatile reference liquid evaporates from the wick structure into a gas that blends into the carrier gas to form a calibration gas.
