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.

Curved conduit ion sampling device and method

The present invention relates to an apparatus and method for use with a mass spectrometer. The ion enhancement system of the present invention is used to direct a heated gas toward ions produced by a matrix based ion source and detected by a detector. The ion enhancement system is interposed between the ion source and the detector. The analyte ions that contact the heated gas are enhanced and an increased number of ions are more easily detected by a detector. The method of the invention comprises producing analyte ions from a matrix based ion source, enhancing the analyte ions with an ion enhancement system and detecting the enhanced analyte ions with a detector.
