Abstract
The invention generally relates to methods and devices for synchronization of ion generation with cycling of a discontinuous atmospheric interface. In certain embodiments, the invention provides a system for analyzing a sample that includes a mass spectrometry probe that generates sample ions, a discontinuous atmospheric interface, and a mass analyzer, in which the system is configured such that ion formation is synchronized with cycling of the discontinuous atmospheric interface.

An online reaction monitoring system, the system comprising:
- a mass spectrometer;
- a reaction vessel that is pressurized with an inert gas and comprises an outlet port;
- a channel that extends from within the outlet port;
- and
- an electrode operably associated with a distal end of the channel, wherein the electrode is not associated with the mass spectrometer, is external to the channel and does not physically contact the channel or a liquid or vapor within the channel.
