"Mass Spectrometer Sampler Cones and Interfaces and Methods of Sealing Them to Each Other" in Patent Application Approval Process (USPTO 20240055248).

A patent application by inventors Hamid Badiei and Brian Chan, assigned to PerkinElmer Scientific Canada ULC, describes a method and apparatus for sealing a mass spectrometer sampler cone to a mass analyzer interface. The invention aims to prevent leaks between components in the system, which can lead to inaccuracies in mass measurements. The system involves using a metal gasket and specific surface features on the sampler cone and mass analyzer interface to provide a substantially fluid-tight seal. The patent application provides detailed descriptions of various configurations and embodiments of the invention. [Extracted from the article]
