A high pumping-speed vacuum system, incorporating a mechanical cryo-pump, was designed and built to attach to the source of a spark-source mass-spectrometer to reduce the partial pressure of carbon- and oxygen-containing gases. Pressures in the 10(-10) mmHg range were obtained, which provide a suitable environment for the determination of carbon and oxygen in tungsten. The effect of the partial pressure of CO on carbon and oxygen determination has been studied and characterized. A determination limit of 1 ppm has been achieved for these elements in tungsten.
