An ion sampling apparatus for use in a mass spectrometry system. The ion sampling apparatus includes a target support for receiving a sample, an irradiation source for emitting energetic radiation or particles toward the target support, and a conduit having a curved end and a longitudinal axis, the curved end having an inlet with a central axis, the conduit being adjacent to the target support. The longitudinal axis of the conduit and the central axis of the inlet intersect to define an angle that is between about 20 degrees and about 210 degrees.
