The Neutral Mass Spectrometer (NMS) is a highly sensitivity
quadrupole mass spectrometer with a mass range to
150 Dalton and unit mass resolution. The NMS
"adaptive" scan mode allows bands of mass
values to be selected to search for unexpected species.
NMS has two instrument modes of operation: (1) open
source (Tilt or survey mode and ion mode) (2) closed
source (Ram Mode).
