The combination of a radio frequency glow discharge (rfGD) external ion source with a Fourier transform ion cyclotron resonance (FTICR) mass spectrometer has resulted in the ability to perform high mass resolution elemental analysis of both conductive and nonconductive materials. Samples investigated in the present study include copper, brass, and a National Institute of Standards and Technology (NIST) glass standard, SRM 1412. Analyses of both the copper and the brass materials resulted in ultra-high mass resolving power (m/Dm > 100,000). A mass resolving power of 280,000 (FWHM) was obtained for the 63Cu+ isotope of the copper sample, the highest reported to date for rfGD studies. In addition, study of the SRM 1412 glass standard revealed mass spectral peaks related to metal oxides present in the glass matrix at concentrations of approximately 4 percent (by weight). The resulting preliminary data demonstrate the capabilities of a rfGD-FTICR instrument and its promise as a powerful tool in distinguishing between isobaric and other mass spectral interferences in insulators, as well as conducting materials.
