ATMOSPHERIC INTERFACE FOR ELECTRICALLY GROUNDED ELECTROSPRAY

摘要

An interface for a mass spectrometer system is provided. The interface can include an inner ceramic tube fabricated from a first ceramic material and an outer tube fabricated from a second ceramic material surrounding the inner ceramic tube. The inner ceramic tube can have high electrical resistivity and high thermal conductivity and the intermediate ceramic tube can have an electrical resistivity that is at least an order of magnitude higher than the electrical resistivity of the first ceramic material and a thermal conductivity that is at least an order of magnitude higher than the thermal conductivity of the first ceramic material.
