Abstract
A method and a device for determining a concentration of a component in a fluid is described. The method comprises the steps of providing from a first optical sensor () a first light intensity (IRA) for light which has interacted with the fluid at a first point in time (A), and a second light intensity (IRB) for light which has interacted with the fluid at a second point in time (B), wherein the first light intensity (IRA) is different from the second light intensity (IRB), and providing from a second optical sensor () a third light intensity (IRA) for light which has interacted with the fluid at the first point in time (A), and a fourth light intensity (IRB) for light which has interacted with the fluid at the second point in time (B). The method also comprises determining the concentration of the component in the fluid, measured by the first optical sensor (), at the first point in time (A) and/or at the second point in time (B), based on the first light intensity (IRA), the second light intensity (IRB), the third light intensity (IRA), the fourth light intensity (IRB), a first concentration function (func), a second concentration function (func), and correlation information (Corr).
