Grand canonical Monte Carlo simulations have been carried out to determine the adsorption selectivity of single walled, arm-chair carbon nanotubes towards a binary Lennard-Jones gas mixture. For species with differing molecular diameters, a complete transition in selectivity is observed as the temperature of the bulk gas is lowered. At high temperatures, the larger energetically favoured species is preferred, however at lower temperatures the smaller species completely eliminates the larger species. This transition is accompanied by a lowering in the total potential energy of the system. For species that have similar molecular diameters, the energetically favoured species is preferentially adsorbed at all temperatures, and transitions in selectivity are absent
