The necessity, design, and characterization of an ultra‐high purity (>99.%, >8‐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 SRM 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.
