A vacuum fusion system suitable for routine analysis of gases present in plutonium, uranium, and zirconium was built and acceptable results were obtained with the exception of the determination of nitrogen in zirconium. Hydrogen is evolved by heating the metal in a vacuum while all gases are released by' fusing the sample at 1900 deg C in a metal bath contained in a graphite crucible. The gases evolved from each sample are collected in individual bulbs for later mass spectrometric analyses. Hydrogen values within 5% and oxygen values within 10% are obtained on zirconium standards. The results for plutonium samples analyzed by the iron and platinum bath techniques are in satisfactory agreement. The apparatus and techniques described provide a method whereby the gases present in 5 separate metallic samples may be collected in one melting operation of less than two hours duration. (auth)
