Claim of US Patent No. 9,748,084

1. A method of installing a direct sample analysis device on a mass spectrometer while maintaining a vacuum in the mass spectrometer,
the method comprising:
coupling a capillary extension to the capillary inlet, in which the capillary extension is configured to couple to the capillary
inlet through a friction fit between outer surfaces of the capillary inlet and inner surfaces of the capillary extension;
and

coupling an end cap extension to the coupled capillary extension, in which the coupled capillary extension and coupled capillary
end cap are configured to provide fluidic coupling between a direct sample analysis sample holder and the mass spectrometer
through the capillary inlet.
