Abstract
A new system of transporting ions from distributed sources to the input hole of a mass spectrometer by a strongly swirled gas jet at atmospheric pressure is proposed. It is shown that the vortex jet transport provides for a more than hundredfold increase in the mass-spectrometric peak intensity, depending on the nature of ions. The effective input aperture for ions increases by three orders of magnitude, which ensures a more complete collection of ionized sample species from distributed ion sources of large volume.
