Mass separators, mass selective detectors, and methods for optimizing mass separation within mass selective detectors

Mass separators are provided that can include at least one electrode component having a surface, in one cross section, defining at least two runs associated via at least one rise, the rise being orthogonally related to the runs. Mass selective detectors are provided that can include at least a first pair of opposing electrodes with each of the opposing electrodes having a complimentary surface, in one cross section, defining at least two runs associated via a rise. Methods for optimizing mass separation within a mass selective detector are also provided, including providing mass separation parameters; providing one set electrodes within the separator having a surface operatively aligned within the separator, the surface, in one cross section, defining at least two runs associated via a rise, the rise being orthogonally related to the runs; and modifying one or both of the rise and/or runs to achieve the mass separation parameters.
