Claim 5:
6. The method according to claim 5, comprising the following steps:
a) preparing a liquid metal bath of an aluminum alloy, an iron alloy, a titanium alloy, or any other metal or alloy capable of containing dissolved hydrogen,
b) circulating a gas in the degassing device, the circulating gas being argon, wherein the circulating gas is in contact with the liquid metal bath and forms a liquid metal bath/circulating gas interface,
c) exchanging hydrogen between the circulating gas and the liquid metal through the liquid metal bath/circulating gas interface such that the hydrogen dissolved in the liquid metal bath diffuses in the circulating gas and enriches the circulating gas with dihydrogen,
d) purifying the circulating gas enriched with dihydrogen in the purification chamber comprising a getter material configured to trap dihydrogen from the circulating gas.
