Abstract:
1. A mass analysis instrument comprising: a housing having sidewalls, the sidewalls of the housing defining an enclosed space of less than one cubic meter, the enclosed space containing all components of the instrument operable to perform mass analysis, wherein the housing and the components of the instrument have a mass less than 50 kgs; within the space defined by the housing, an atmospheric ionization source operatively coupled to a drag pump; within the space defined by the housing, a vacuum manifold operatively coupled to the atmospheric ionization source, the vacuum manifold including two regions, a first of the two regions configured to interface with the atmospheric ionization source, a second of the two regions operatively interfacing with the first region, the first region maintained at a pressure less than the source, the second region maintained at a pressure less than the first region; and within the space defined by the housing, a mass analyzer within the second region.
