Abstract

The invention relates to an ATR spectrometer, containing an optical probe having a sensor made of transparent material and a feed line and an exit line for light, wherein the sensor contains an optical polymer or a mixture of different optical polymers. The probe of the spectrometer according to the invention essentially has the advantages that it is inexpensive and extremely flexible, and that it can be matched to the concentration range of the solution to be examined, which makes it possible to fill the gaps in terms of measurable concentrations between conventional transmission spectroscopy and prior ATR spectroscopy.
