Mass spectrometer interface for an ion source

摘要

A mass spectrometer sample input interface is disclosed including a desolvation apparatus defining a desolvation pathway 5 along which a desolvation gas flows. The gas flows in a direction from upstream to downstream and the desolvation pathway has a desolvation pathway portion. An ion pathway apparatus for defining an ion pathway for analyte solution droplets 12 to follow is also disclosed, the ion pathway leading into the mass spectrometer. The ion pathway includes an ion pathway portion that follows the desolvation pathway portion. This increases the number of usable analyte ions for mass spectrometer analysis.
