Abstract

In this paper, a new construction of a contactless conductivity detector based on true three dimensional arrangement of the electrodes is presented. In the presented microsystem, the microchannels filled with an eutectic solution (Gallium-Indium, Aldrich) serve as the electrodes (called pseudoelectrodes). The detector is made in PMMA using micromilling technology and then thermal bonding. The presented microchip was tested using ion chromatograph equipped with a conductivity detector. The microdetector was connected in series with a large-scale ion chromatographic detector. Three synthetic mixtures of anions: fluoride, acetate and formate (F", CH 3 COO - and HCOO - ) of different concentrations were analysed.
