A recently granted patent (Publication Number: US11972937B2) discloses a filament assembly designed for mounting to a source assembly of a mass spectrometer. The filament assembly features a body with an aperture or spigot for connection to the source assembly, along with at least two electrical contact pads for secure electrical connection. The design includes keying features for proper alignment, a unique cross-sectional shape, and a bore for securing the assembly with a screw. Additionally, the filament assembly includes filament mounting arms for attaching a filament element and a filament shroud for protection.

Furthermore, the filament assembly can be integrated with a volume housing for a repeller assembly, with the option of connecting to a base with spring-loaded electrical terminals. This configuration allows for easy connection and disconnection of the filament assembly, providing flexibility and convenience in mass spectrometer operations. The filament element itself is made of a metal coated with yttrium oxide or thorium dioxide, or comprises a mesh structure, enhancing its performance and durability in analytical processes. Overall, the patented filament assembly offers a robust and efficient solution for mass spectrometer applications, with a focus on secure mounting, electrical connectivity, and reliable filament performance.
