Flow Cytometer With Multiple Intensity Peak Design

摘要

A sensing system comprises at least one fluidic channel (104) for providing at least one analyte (105) into at least one region of interest; at least one radiation transport system (501), for providing excitation radiation (103) for exciting analytes traversing the at least one region of interest; and a radiation collection system (301) for collecting any radiation signal emitted from the at least one region of interest. The at least one radiation transport system is adapted for providing excitation radiation comprising a plurality of excitation radiation intensity peaks (101, 102), whereby the distance between the excitation radiation intensity peaks is known. The sensing system comprises means (302, 303) for measurement of the speed of the at least one analyte within the fluidic channel (104), the means for measurement of speed comprising timing means (303) for obtaining the time between maxima in radiation signals emitted by the at least one analyte.
