Abstract

The development of a new measurement modality for the fiber drop multianalyser is reported. The optrode used in earlier studies has been modified to permit simultaneous measurement of optical and capacitance information during drop formation. Measurements on a range of liquids are reported, and variations in the capacitance of the order of several percent are achieved. The dynamic range of this measurement channel is approximately 5500, although noise considerations reduce ths approximately by a factor of three. The ability of the new technique to discriminate between test solutions is analysed.
