ABSTRACT:
A coded mass spectrometer incorporates a spatial or temporal code to reduce the resolution/sensitivity dichotomy inherent in mass spectrometry. The code is used to code one or more portions of a mass spectrometer. Coding patterns, such as Hadamard codes, Walsh codes, and perfect code sequences can be used. The coding can be spatial, for example, by using an aperture mask and/or temporal, for example, by coded injection of ions for analysis.
