Abstract :
The continuous flow sensor for optical absorbance or transmittance measurements is presented. The structure is made of LTCC (Low Temperature Co-fired Ceramics). The ceramic sensor consists of microfluidic channel, absorption cell and two polymer optical fibers. The input and output optical fibers are connected with light emitting diode and digital photodetector. Performed tests have shown nearly linear response to KMnO4 solution up to ca. 160 mM. The absorbance measurements were made with usage of low-cost and miniature optoelectronic components which enable future integration with the ceramic structure.
