Abstract
The present invention provides a mass spectrometer and a method for establishing a vacuum system thereof, the mass spectrometer having a hermetical chamber in communication with an external environment only through a vacuum interface, the chamber comprising a first chamber and a second chamber, the second chamber having an adsorption pump disposed therein, the first chamber being in communication with the second chamber through a flow restricting structure. The present solution can be applied to bench-top and even portable mass spectrometers, taking into account the low energy consumption, miniaturization and vacuum requirements of such mass spectrometers.
