Tandem time-of-flight mass spectrometry with non-uniform sampling


A method and apparatus are disclosed for parallel all-mass tandem mass spectrometry employing multi-reflecting time-of-flight analyzer for both ms stages, preferably arranged within the same analyzer to secure ultra-high resolution. Sensitivity and speed of tof-tof tandem are enhanced by non-redundant multiplexing based on signal sparseness and on avoiding repetitive signal overlaps at multiple repetitions of true fragment signals.
