Abstract
A process and system for the purification of germane containing phosphine to provide a purified germane product. One aspect of the present invention is a process for making a purified germane product containing less than 50 ppb of phosphine which comprises providing a phosphine contaminated germane gas hydrogen gas mixture; passing the germane gas hydrogen gas mixture through an adsorbent which selectively adsorbs phosphine and withdrawing therefrom a purified germane gas hydrogen mixture; and separating the purified germane gas from the hydrogen germane gas mixture.
