Abstract:
A capillary waveguide fluorescence sensor which includes a capillary and an optical/fluid connector connected to an end of the capillary. The optical/fluid connector includes a fluid sample injection port for longitudinally injecting a fluid sample into the capillary bore and at least one optical fiber for either longitudinally delivering light energy into the capillary or longitudinally collecting fluorescence emission from the fluid sample injected into the capillary bore. The sensor may also include at least one capillary outer surface collection optical fiber for perpendicularly collecting fluorescence emission from the fluid sample injected into the capillary bore. The capillary outer surface collection optical fiber is positioned adjacent the outer surface of the capillary wall such that the central axis of the collection optical fiber is substantially perpendicular to the central axis of the capillary bore. In a method for sensing fluorescence emission from a fluid sample, the fluid sample is longitudinally injected into a bore of a capillary and the fluid sample is excited by longitudinally delivering light energy into the capillary. Fluorescence emission caused by the excitation from the fluid sample may be collected by at least one optical fiber positioned substantially perpendicularly to the central axis of the capillary bore or it may be longitudinally collected by at least one optical fiber positioned substantially parallel with the central axis of the capillary bore.
