Paper Abstract

A novel separations-based fiberoptic sensor (SBFOS) is described for remote analysis that incorporates capillary electrophoresis (CE). High sensitivity is possible with laser induced fluorescence detection and a unique and powerful element of selectivity is afforded by the exceptional separation power of CE. Speed of analysis and the possibility of remote control are further attributes which render the system useful for sensing applications. Details are given in this report for a SBFOS that employs a single-fiber optical configuration and a single buffer reservoir CE arrangement. The fiberoptic probes the outlet of a short separation capillary in a simple frontal mode of operation. Design considerations and the results of preliminary evaluations of the separation and detection characteristics of the SBFOS are presented.
