Ionization chamber

摘要

An ionization source has a chamber for ionizing a fluid sample, the chamber having surfaces to reduce the overall interaction with reactive samples. The inner surface walls of the ionization chamber may be formed from an inorganic conductive nitride or disulfide material or may be applied to a substrate as a coating. A method for reducing the interaction of a reactive analyte with an ion source comprises coating the source with an inert conductive material.
