Abstract
The invention provides a trapped ion mobility separator (TIMS) and methods to operate it wherein an ion region of the TIMS, through which ions travel along an axis from an entrance to an exit, has an elongate cross-sectional profile perpendicular to the axis with a long dimension and a short dimension. First and second counteracting forces on the ions along the axis are provided, wherein at least one of the first and second forces has an effect on the ions that is ion mobility dependent, and wherein at least one of the first and second forces varies spatially along the axis such that ions are trapped and separated by ion mobility. Different embodiments provide the first and second forces using different combinations of gas flow and electric field potential, and employ various electrode structures that provide the system with different advantageous characteristics.
