Patent ID: 7112266

Claim:
A device for analyzing one or more samples, comprising: a plurality of channels, each channel comprising an inlet end and an outlet end; wherein each of said channels defines, at least in part, a sample-migration pathway that extends longitudinally along at least a portion of such channel; a detection zone downstream of said inlet ends; wherein each of said sample-migration pathways traverses at least a portion of said detection zone; an excitation-beam pathway that extends through at least a portion of said detection zone and intersects each of said sample-migration pathways; a detector disposed to simultaneously detect radiation emitted from a plurality of spaced-apart observation regions within said detection zone, each of said observation regions being located whereat said excitation-beam pathway intersects a respective one of said sample-migration pathways; and a plurality of crosstalk zones, each crosstalk zone being located between a respective pair of adjacent observation regions; wherein said detector is configured to disregard radiation emitted from said crosstalk zones.
