Abstract
The gas jet enhanced glow discharge system for direct solid analysis has been designed and constructed in our laboratory. Contrary to the conventional glow discharge, the laminar flow of argon gas through the 0.5 mm gap impacts a surface of solid sample. In addition, a needle valve is placed between a glow discharge cell and a vacuum pump to control the pressure of a glow discharge cell. As a result, the pressure could be precisely controlled without changing the flow rate of argon gas. Due to the presence of laminar flow of argon gas onto the surface of the sample, the analytical performances are quite different from those observed in a conventional glow discharge system. Emission behaviors of resonance and non-resonance lines for Cu, Zn and Ar are mainly discussed. In this report, the preliminary experimental results including emission characteristics and sputtering efficiency are presented.
