A lens assembly for use in mass spectrometry and a method for reducing contaminant build up on ion optic components in a lens assembly for use in a mass spectrometer are disclosed herein. In various embodiments of applicant's teachings, the lens assembly comprises a plurality of ion optic components assembled to form an ion lens and a heater. The plurality of ion optic components has a generally similar expansion coefficient. The heater is operatively coupled to the ion optic components. The heater heats the ion optic components to reduce the accumulation of debris on the ion optic components. In various embodiments, the method includes receiving, in a lens assembly, ions from an ion source. The lens assembly includes a plurality of ion optic components assembled to form an ion lens, the plurality of ion optic components having a generally similar expansion coefficient. The method also comprises heating the ion optic components to a first temperature.
