MANIFOLDS AND METHODS AND SYSTEMS USING THEM

摘要

Certain embodiments described herein are directed to manifolds that comprise a moveable, internal sealing member that can be used to engage one or more ports of the manifold and prevent or reduce fluid flow from the engaged port into the manifold. In certain examples, the manifold can be used in a mass spectrometer to control fluid flow from an interface and a turbomolecular pump.
