ABSTRACT:
A method of quantitatively analyzing oxygen or nitrogen contained in titanium group metal or an alloy thereof, involving melting the metal or alloy in an inert gas atmosphere, allowing the oxygen in titanium to react with carbon thereby extracting it as carbon monoxide, or allowing the nitrogen in titanium to be extracted, and subjecting the extracted carbon monoxide or nitrogen to a quantitative analysis, characterized in that a titanium sample for analysis is melted in the present of nickel in an amount corresponding to 7 to 17 times the weight of the sample.
