Abstract
A mass spectrometer and associated methods analyze an ion beam by accumulating ions for a sequence of time periods, and driving the accumulated ions in pulses. Differing quantities of ions can be accumulated in the sequential pulses according to a psuedo-random sequence, and the slower ions are overtaken by the faster ions of a subsequent pulse. A mass spectrum may be reconstructed from an overlapping ion detector signal using an inverse of a weighted simplex matrix or inverse Hadamard transform techniques.
