Abstract

Significant improvement in reducing background build-up and a decrease in burn time have been achieved with a new compact gas jet developed by the U. S. Geological Survey. Moving-plate studies on geologic materials revealed a considerable increase in the rate of controlled vaporization of the elements as compared with other jets under the same excitation conditions. The use of the jet produces a stabilized arc, as well as the depression of the cyanogen bands, in a nitrogen-free atmosphere. The simplicity of the gas jet electrode holder simplifies the change of the electrodes between samples.
