CONTROLLED ATMOSPHERE FOR SPECTROCHEMICAL ANALYSIS

Abstract

A technique for spectrochemical analysis of various materials was developed which will eliminate the cyanogen bands formed during carbon arcing. Controlling the atmosphere with a quartz vessel proved to be very valuable in carbon arc excitations. It reduces the background intensity and permits longer exposures. With an atmosphere free of nitrogen, the cyanogen bands are eliminated and many of the analytical lines of elements in this region become available, such as lead, cesium, and thallium, between 3000 and 4500 Angstroms. The use of inert atmospheres on highly inflammable materials such as gasoline would permit direct arcing. (Author)
