<p>The invention concerns a method for calibration of an analysis system (1) having a diaphragm (2), the outside of which is immersed into a medium (3) to be analysed, and on the inside of which a carrier fluid (9) for the admission of a species penetrating the diaphragm (2) is flowing. On this system a calibration in situ should be possible, without causing high costs for constructional measures. For this purpose, the carrier fluid is, in a calibration step, retained on the inside of the diaphragm (2) for a predetermined sojourn time, and then the load of species in the carrier fluid (9) is determined. In a further calibration step, the carrier fluid is led past the diaphragm at a speed also used for measurements, and the load of species in the carrier fluid is measured. Then the penetration behaviour of the diaphragm is determined on the basis of both load values.</p> |
