Abstract: PCT No. PCT/EP96/02550 Sec. 371 Date Mar. 13, 1998 Sec. 102(e) Date Mar. 13, 1998 PCT Filed Jun. 13, 1996 PCT Pub. No. WO97/00437 PCT Pub. Date Jan. 3, 1997The 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.

Abstract: An ATR spectrometer contains an optical probe with a sensor made of a transparent material, a light feeding line and a light carrying-off line. The spectrometer is characterised in that the sensor contains an optical polymer or a mixture of different optical polymers. The probe of the disclosed spectrometer has the advantage of being economical and extremely flexible, so that it may be adapted to the concentration range of the solution to be tested. The existing gap between concentrations that may be measured by conventional transmission spectroscopy and by state of the art ATR spectroscopy is thus closed.
