Patent DE-19740266-A1 (DE)
Title: Measurement of tenside presence in laundry water
Inventor: EBERL RONALD DR
IPC: G01N21/552
Filed: 1997-09-15
Abstract: A measuring process demonstrates the presence of tensides in aqueous solution. One or a series of measurements are initiated, as soon as all or part of the light waveguide sensor which was in the solution is no longer in the solution. The detection process uses the absorption of e.g. infrared emissions by water especially at the wavelengths 1.4  mu m, 1.93  mu m and 3  mu m using the attenuated total reflection process. The sensor is dipped in the solution from time to time and removed, with immediate evaluation of the signal. The water only remains covering the sensor surface in the presence of a relatively large concentration of tensides, generating a characteristic signal.
