1. A method of identifying individual substances within a mixture of substances comprising the steps of:

  • (a) causing the mixture to travel past a spaced plurality of detectors, each detector Ik being arranged to produce a signal Sk representative of a characteristic of the mixture as the mixture passes the detector Ik ;

    (b) repeatedly measuring the signal Sk (t) at each detector Ik at a plurality of times t=t1, t2, t3 . . . ;

    (c) associating each signal Sk (t) with a respective nominal velocity Vk (t), wherein Vk (t) is calculated as that constant velocity which a substance traveling within the mixture would need to reach the detector Ik at time t;

    (d) grouping the signals Sk (t) by nominal velocity Vk (t); and

    ,(e) identifying individual substances within the mixture according to peaks within a histogram of the grouped signals.
