A combined detection system involving simultaneous LIF and contactless-conductometric measurements at the same place of the microfluidic chip was described.The LIF measurement was designed according to the confocal principle and a moveable contactless-conductivity detector was used in C⁴D.Both measurements were mutually independent and advantageous in analyses of mixtures.Various experimental parameters affecting the response were examined and optimized.The performances were demonstrated by simultaneous detection of Rhodamine B.And the results showed that the combined detection system could be used sensitively and reliably.
