Abstract

The necessity, design, and characterization of an ultra-high purity (>99.999999%, >S-nines) discharge gas delivery system for quadrupole-based glow discharge mass spectrometer are described. This system greatly reduces common contaminants arising from residual gases (e.g., CO+, ArC+, ArN+, ArO+, etc.). The utility of the system is shown in the analysis of NIST S RM 685-W high-purity gold. Sub-ppm detection levels are readily achieved and maintained for all metals. Low background levels for some non-metals, including C, N, and O, are also reported. The ability to quantify such species is shown in the generation of a calibration curve for carbon using NIST steel standards.
