A method for desulphurising a nitrogen oxide accumulator catalytic converter of an exhaust gas system that includes the nitrogen oxide accumulator catalytic converter and at least one selective catalytic reduction catalytic converter disposed downstream of the nitrogen oxide accumulator catalytic converter, of an internal combustion engine, where a desulphurisation strategy, on the basis of which the nitrogen oxide accumulator catalytic converter is desulphurised, is adjusted to the ageing of the nitrogen oxide accumulator catalytic converter.
