With regard to the detection of a physiological active substance of biological origin and the measurement of its concentration in a sample, the invention provides a technique for moving gel particles that are produced in the sample without using a mechanical stirring member, and allows a highly accurate detection of the physiological active substance of biological origin and measurement of its concentration with a simple arrangement. By partial heating/cooling of a sample cell, thermal convection is generated within a mixture liquid in the sample cell, and as a result the gel particles that are produced in the mixture liquid are moved. In addition, based on the intensity of forward scattered light, the rate of change in the number of gel particles is measured.

The invention relates to a method for operating a FTIR (Fourier transformation infrared) spectrometer, wherein a validation/calibration of the spectrometer is carried out in cyclically recurring intervals in that by way of at least two temporarily available gases a reference spectrum with a zero gas and also an absorption spectrum with a calibration gas are recorded. The invention further relates to a spectrometer according to the preamble of the patent claims 1 and 8. In order to achieve that at each site of use and at any time a calibration or validation of the spectrometer can be carried out, the invention proposes to use so-called substitute gases during the validation of the spectrometer as gas components, said substitute gases only simulating the actual measured gas component with respect to the metrological properties.
