The present invention relates to a) at least one reducing agent, and b) the device (1) for providing a gas mixture comprising at least one of the at least one reducing agent precursor. An aqueous solution reservoir 20 for the unit 45 includes means for administering the at least one reducing agent precursor, and an aqueous solution (45) which can be connected flexibly to the evaporator chamber 24 to the evaporator chamber (24). Aqueous solution of the evaporator chamber 24, 45 is at least partly provided with means (27, 63) for heating the evaporator chamber (24) that can be heated to a temperature above the critical temperature to be evaporated. Method of the device 1 and the invention according to the present invention makes it possible that the reducing agent is provided for the selective catalytic reduction of nitrogen oxide in the exhaust gas of an internal combustion engine. In a preferred embodiment, the evaporator unit 12 is configured as an evaporator chamber 24 and a hydrolysis catalyst group 17 is configured on the outside of the exhaust system. As a result, the amount of hydrolysis catalyst group 17 is reduced, enabling a compact configuration.
