Abstract
A tap cone (5) for a mass spectrometer, such as an ICP mass spectrometer, includes a base section (50) and a cone section (52) projecting from the base section. The tapered section (52) has a generally tapered inner portion and a generally tapered outer portion. The tapered section is provided with a top region (53) in which an aperture (51) is provided. The tap cone is substantially entirely made of silicon. The utility model also relates to a plasma interface and a mass spectrometer.
