Abstract
A method is disclosed for calibrating an analysis system having a membrane, the outside of which is in contact with a medium to be analyzed, in order to detect a concentration of a species there, and a corresponding analysis system. In this connection it is desirable to be able to perform a calibration in situ. In this calibration, a first fluid of a predetermined first concentration of the species is conveyed along the inside of the membrane, at least a second fluid of a predetermined second concentration which differs from the first concentration is likewise conveyed past the inside of the membrane and the concentrations of the two fluids after passing the inside of the membrane are recorded. From these concentrations, parameters for a correlation between the concentration on the outside of the membrane and a measurement signal are ascertained.
