CHEMICAL ANALYSIS INSTRUMENT WITH MULTI-PURPOSE PUMP

摘要

A mass spectrometer for analyzing a sample may include an analysis chamber for analyzing the sample and a first vacuum pump operably connected to the analysis chamber, wherein the first vacuum pump operates to create a first vacuum state. The mass spectrometer may also include a sample-preparation chamber operably connected to the analysis chamber and a second vacuum pump that operates to create a second vacuum state, wherein the first vacuum state is a lower pressure than the second vacuum state. The second vacuum pump may be operably connected to the first vacuum pump in a first configuration, and the second vacuum pump may be operably connected to the sample-preparation chamber in a second configuration.
