Abstract
A method for determining hydrogen content in a compound is disclosed. This method generally comprises heating the sample to sufficient temperatures to effect pyrolytic conversion of any hydrogen containing compounds in the sample to hydrogen gas, and measuring the hydrogen content evolved by this conversion. In a preferred embodiment, this is carried out in a tube furnace inerted and purged with a noble gas. An apparatus for determining hydrogen content in a compound is also disclosed.
