Oxygen in lead, bismuth and their compounds and in alloys of lead was determined by carrier gas methods. Oxygen in some lead and bismuth compounds could not be determined by the usual method for organic compounds. However, oxygen in lead and in its compounds was determined accurately by a carrier gas method using naphthalene as reaction agent. A carrier gas method adding carbon as solid reaction agent was applied to lead compounds, bismuth and bismuth compounds, and favorable results could be obtained. Oxygen in alloys of lead, such as Kelmet alloy and soft solder, could be accurately determined by a carrier gas method with naphthalene and by one using hydrogen as reaction gas, respectively. One analysis took about 40 min by a gravimetric method and about 20 min by a coulometric method.
