GERMAN CLEANING |
| abstract |
A method and system for purifying phosphine-containing german to provide a purified german product are disclosed. One aspect of the present invention is a process for preparing a purified German 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 extracts therefrom a purified germane gas-hydrogen gas mixture; and separating the purified germane gas from the hydrogen-germane gas mixture. |
