The presented paper describes a novel optical titration sensor based on planar polymer waveguides integrated on a printed circuit board. The advantage of titration as an analytical method is that small quantities of a substance can be determined with inexpensive equipment (100 to 3000 EUR) in a short time (within a few minutes) with good accuracy and repeatability (1% to 0.05%). The first section gives an overview over the compact opto-electronic sensor. It is integrated...
