ABSTRACT:
A process for improving moisture analyzers or hygrometers that use optical absorption techniques to measure water vapor. Water vapor in the optical path outside the sample region is treated to exchange the hydrogen atoms for deuterium, so that the adsorbed water vapor is converted to heavy water, D.sub.2 O, and isotopically mixed HDO, thus reducing or eliminating the interference in any optical absorption apparatus for measuring water vapor, provided the spectral resolution is sufficient to resolve normal water absorptions from heavy water absorptions.
