Ultrahigh Mass Resolution (m/delta m 1/2) > (400,000) Glow Discharge Mass Spectrometry: Direct Analysis of Heavy Isotope Mixtures

Abstract

Fourier transform ion cyclotron resonance (FTICR) mass spectrometry, when coupled to a glow discharge ion source, has demonstrated a mass resolution (m/Delta m sub 1/2) which exceeds that of any currently available instrumentation by a factor of 20. Such high mass resolution is essential for the direct analysis of heavy isotopes without preseparation, where overlapping isobaric peaks, which differ in mass by only a few parts in 500,000, must be resolved....
