Abstract
A mass spectrometer includes an Electron Impact (“EI”) or a Chemical Ionisation (“CI”) ion source, and the ion source includes a first coating or surface. The first coating or surface is formed of a metallic carbide, a metallic boride, a ceramic or DLC, or an ion-implanted transition metal.
Claims22
A mass spectrometer comprising an Electron Impact (“EI”) or a Chemical Ionisation (“CI”) ion source, wherein said ion source comprises a first coating or surface provided on at least a portion of said ion source;
- wherein said first coating or surface comprises a metallic carbide coating or surface.
A method of mass spectrometry comprising:
- ionising ions in an Electron Impact (“EI”) or a Chemical Ionisation (“CI”) ion source having a first coating or surface provided on at least a portion of said ion source;
- wherein said first coating or surface comprises a metallic carbide coating or surface.
A method of making an ion source or one or more ionisation chambers or one or more repeller electrodes forming part of an Electron Impact (“EI”) or a Chemical Ionisation (“CI”) ion source for a mass spectrometer comprising:
- depositing, sputtering or forming a first coating or surface on at least a portion of an ion source or one or more ionisation chambers or one or more repeller electrodes forming part of said ion source;
- wherein said first coating or surface comprises a metallic carbide coating or surface.
