We have proposed a novel concept of Resonance Ionization Mass Spectrometry using an Inductively Coupled Plasma as an Atomic Source (ICP-RIMS). Isotope ratio analysis using ICP-RIMS is expected to be a convenient and precise technique with high throughput. However, the mass discrimination effect caused from difference in kinetic energy of neutral atoms in ICP-RIMS is crucial for precise isotope analysis. We, therefore, investigated the atom kinetic energy distribution introduced into the laser ionization region. The mass-dependent kinetic energy was confirmed in the initial kinetic energy distributions. We preliminary estimated a mass discrimination effect caused by mass-dependent kinetic energy in ICP-RIMS for various detector sizes. We proposed that this effect can be suppressed by selecting the appropriate detector size and adopting the scanning mode of the deflecting voltage.
