Abstract
This invention describes a vacuum interface for a mass spectrometer system formed from a diverging nozzle. The vacuum interface may be used to transfer a beam of ions from an atmospheric pressure ionisation source into a vacuum chamber for analysis by a mass analyser.
Claims34
An interface component for coupling an ion source to a mass analyser, the interface component comprising a diverging nozzle which operably accelerates ions generated within the ion source to supersonic speeds and collimates them prior to their introduction into the mass analyser.
A mass spectrometer system comprising an ion source and a mass analyser, the ion source and analyser being coupled to one another via an interface component, the component comprising:
- a. a diverging nozzle which operably accelerates ions generated within the ion source prior to their introduction into the mass analyser.
An interface component for coupling an atmospheric ion source to a mass analyser, the interface component including a diverging nozzle which operably accelerates ions generated within the ion source to supersonic speeds prior to their introduction into the mass analyser.
A method of manufacturing an interface component for coupling an atmospheric ion source to a mass analyser, the method comprising:
- a. Defining a nozzle having a throat and a diverging portion
- b. Fabricating at least side walls of the throat from a material having a hardness value of at least 8 on the Mohs scale;
- c. Polishing the side walls of the throat.
