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.

摘要： Mass spectrometry is performed utilizing an electron ionization (EI) source. The EI source ionizes a sample at different electron energies, including below and above 70 eV. The EI source may be utilized for soft ionization as well as hard ionization. The value of the electron energy may be selected so as to favor the formation of molecular ions or other ions of high analytical value. The ion source may be an axial ion source.
