WIDE RANGE ELECTRON IMPACT ION SOURCE FOR A MASS SPECTROMETER - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240038522 titled 'WIDE RANGE ELECTRON IMPACT ION SOURCE FOR A MASS SPECTROMETER
Simplified Explanation
The abstract describes a wide-range ion source for a mass spectrometer. It consists of two portions, with the second portion positioned downstream of the first portion. The first portion includes an anode and a first filament that is exposed to the pressure of a process chamber. The second portion includes a tubular anode, a second filament surrounding the tubular anode, an extraction lens, and a focus lens.
- The first portion of the ion source includes an anode and a first filament that is exposed to the pressure of a process chamber.
- The second portion of the ion source includes a tubular anode, a second filament surrounding the tubular anode, an extraction lens, and a focus lens.
- The first filament is positioned proximate to the anode and secured in place relative to the anode.
- A first electron repeller with a partially circular shape is present.
- The extraction lens defines an opening and the focus lens conducts ions into a volume.
Potential Applications:
- Mass spectrometry: The wide-range ion source can be used in mass spectrometers for various applications such as chemical analysis, environmental monitoring, and pharmaceutical research.
- Elemental analysis: The ion source can be utilized for elemental analysis of samples, providing valuable information about the composition and structure of materials.
