Chemical reaction schemes are typically simplified by considering the controlling steps of the process, the 'fast' reactions being taken into account by quasi-equilibrium assumptions. Traditionally, intuitive reasoning is employed to arrive at the simplified system. This may, however, be cumbersome and sometimes misleading. In this paper a systematic approach is presented that guarantees that the simplified model coincides with the asymptotics of the original one.
