The invention relates to analyzing a substance. An optical medium is arrange on a substance surface with at least one region of the optical medium surface in contact with the substance surface. An excitation light beam is emitted through the contacting region of the medium surface to the substance surface. A measurement light beam is emitted through the optical medium to the contacting region of the medium surface such that the measurement light beam and the excitation light beam overlap on the interface of the optical medium and of the substance surface, on which the measurement light beam is reflected. A deflection of the reflected measurement light beam is detected in dependence on the wavelength of the excitation light beam. The substance is then analyzed based on the detected deflection of the measurement light beam in dependence on the wavelength of the excitation light beam.

Infrared measuring device, especially for the spectrometry of aqueous systems, preferably multiple component systems
The invention relates to an infrared measuring device, especially for the spectrometry of aqueous systems. Said device comprises at least one measuring unit, especially a measuring cell, also comprising at least one ATR-body and at least one infrared light source. The measuring unit contains at least one ATR-body which comprises at least two planar, substantially parallel limiting surfaces and which is transparent with respect to measuring radiation and which has an index of refraction which is greater than that of the medium which is arranged next to at least one limiting surface and which is to be examined, especially larger or equal to 1.5. The IR-measuring radiation on at least one of the planar, parallel limiting surfaces of the ATR-body can be totally reflected in an attenuated manner by at least six times.
