Abstract:
1. A multiple flow channel particle analysis structure, comprising: a plurality of flow channels formed inside of a microfluidic chip, wherein each of the plurality of flow channels, includes a detection region having a first optical window aligned to admit a beam of light into said detection region of said flow channel; a detector system including one or more detectors, said detector system optically coupled to each of said plurality of flow channels at said detection region wherein said detector system generates a signal for each of said plurality of flow channels which varies based on at least one of light passing through or light emitted from said flow channel; and an analyzer adapted to concurrently analyze a plurality of said signals generated by said detector system optically coupled to said plurality of flow channels; wherein the concurrently analyzing the plurality of said signals includes using one or more of a light extinction signal, a light scatter signal or an emitted light signal to assess threshold events in said plurality of flow channels and to independently trigger processing steps for individual flow channels of said plurality of flow channels.
