The separation of ion species according to their mobilities in a buffer gas is a technique that has been around for over thirty years. It has been successfully used in portable devices for rapid detection of chemical warfare agents and for the detection of explosives and illegal drugs. More recently the technique has been applied to more fundamental investigations into the structure and conformation of biomolecules. The classical Ion Mobility Separator uses a static DC voltage gradient to drive ions through the buffer gas. Reported here is a new approach to mobility-based separation of ions using a travelling voltage wave in an ion guide.
