ABSTRACT:
An apparatus for performing chemical analyses includes a mass spectrometry module and an interface module that processes sample materials for delivery to the mass spectrometry module. The interface module includes a vessel having an opening to access a vessel chamber, a door to block the opening, a sealing member disposed between the door and the vessel, and an interlock. The interlock is actuated by the sealing member if the door is in the closed position and the sealing member is properly disposed between the door and the vessel to seal the vessel. The sealing member alternatively includes an indicator portion that is visible to an operator if the door is in the closed position and the sealing member is properly disposed.
