Description
Summary:The design and preliminary charaterization of a novel fiber optic-based fluorimeter are reported. It includes a white light source, optical fibers for light transmission and an intensified photodiode array for detection. A bifurcated sensing configuration is used to transmit excitation and emission radiation to and from the analyte solution. Detection limits in the nanomolar range are reported for several test compounds.
