Abstract
A novel ion source designed for use in mass spectrometric determination of organic compounds is described. The source is designed around a low pressure, large volume, hot cathode Penning discharge. The source operates in the 10-4 -10-7 torr pressure domain and is capable of producing focusable current densities several orders of magnitude greater than those produced by conventional "Nier"-type sources. Mass spectra of n-butane and octafluoro-2-butene are presented. An improved signal-to-noise ratio is demonstrated with a General Electric Monopole 300 mass spectrometer.
