摘要：

Use of a hollow cathode ionization source with a quadrupole mass filter forms a solids mass spectrometer well suited for trace element analysis of bulk metals. Cathode geometry, particularly bore diameter and nozzle-orifice length and discharge current effects were studied to yield optimum ion sensitivity. Reproducibility for minor to trace constituents in steel and brass standards was 2-6 % RSD. Sensitivities were in the low ppma to sub-ppma range. © 1979, American Chemical Society.
