Abstract: A device for conducting a transmission measurement includes a system for generating a light wave consisting of a first and a second wavelength fraction, in addition to an optical channel guiding the light wave to a sample tube with a sample, wherein the light wave permeates the sample tube with a sample. The device also has a motion unit for producing a relative movement of the light wave along the sample tube. A receiver for receiving and separating the first and second wavelength fragments after the light wave has permeated the sample tube with a sample is also provided. A converter converts the first wavelength fraction into a first digital measuring value describing the degree of transmission in the first wavelength and converts the second wavelength fraction into a second digital measuring value describing the degree of transmission in the second wavelength. Quotients are formed from the first digital measuring values and the second digital measuring values by an evaluation system and the first derivative of the quotients is calculated.
