Abstract

An apparatus and a method for identifying a CO2 content of a fluid. The apparatus includes: an absorber device having a porous material, the absorber device being capable of being brought into contact with the fluid; pores of the porous material having at least one hydrophilic first chemically functional group; the first chemically functional group being joined to the porous material; the first chemically functional group having the property of reacting in alkaline fashion with water; an electrode device that is disposed on the absorber device for electrical contacting of the absorber device; and an evaluation device that is electrically connected to the electrode device and by which an electrical property of the absorber device is measurable to identify the CO2 content of the fluid.
