Molecular-beam methods and novel electrodes simplify analysis of mixtures by Mitch Jacoby describes the work of a team that recently developed and tested an advanced-generation GC-MS interface device that transports sample compounds eluting from a GC column to a mass spectrometer by way of a supersonic molecular beam. This methodology promises to circumvent two particularly intractable problems in GC-MS analysis.
- The relatively small range of volatile and thermally stable compounds that are amenable to analysis; and
- The relatively weak molecular ion observed from many analytes.
