Abstract
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.
