An emission spectrometric method for the determination of O/sub 2/ in Ti and Ti alloys is based on the direct current carbon arc excitation of a special electrode assembly which provides a molten Ft bath after the arc is initiated. The O/sub 2/ in the Ti sample is rapidly liberated from this bath into an Ar atmosphere which supports the arc discharge. The intensity ratio of the line pair is related to the O/sub 2/ content of the Ti sample. This procedure provides O/sub 2/ determinations with a precision comparable to the vacuum fusion or bromination-reduction techniques, but has the advantage of greatly reduced time requirements.
