Abstract
A feed system for picking a sample tube off a magazine and introducing the sample tube into the inlet system of a mass spectrometer. The feed system comprises a pick-up tube (52) designed at its forward end to fit over a sample tube (16) resting on the magazine (22) and grip the sample tube (16). A carriage (40) supports the pick-up tube in a horizontal attitude and is driven towards and away from the inlet system (10) of the mass spectrometer by means of a motor driven pinion (46) engaging a rack (44) on the upper surface of the carriage (40). A cam track (50) raises the pick-up tube (52) after a sample tube (16) has been gripped to the level of the aperture (12) of the inlet system (10).
