Abstract
The invention generally relates to system and method for lossless ion mobility spectrometer with axial diffusion constriction. In certain aspects, the invention provides an ion mobility spectrometry system, the system comprising: an ion mobility drift cell comprising electrodes; and a central processing unit (CPU), and storage coupled to the CPU for storing instructions that when executed by the CPU cause the electrodes of the drift cell to apply varying electric fields within the drift cell to constrain ions as they get separated in the drift cell and thereby restrict axial diffusion of the ions in the drift cell.

An ion mobility spectrometry system, the system comprising:
- an ion mobility drift cell comprising electrodes;
- and
- a central processing unit (CPU), and storage coupled to the CPU for storing instructions that when executed by the CPU cause the electrodes of the drift cell to apply varying electric fields within the drift cell to constrain ions as they get separated in the drift cell and thereby restrict axial diffusion of the ions in the drift cell.
A method of separating ions while restricting axial diffusion of the ions, the method comprising:
- generating a plurality of ions that are transferred to an ion mobility spectrometer comprising an ion mobility drift cell comprising electrodes;
- and
- applying, via a central processing unit (CPU) of the ion mobility spectrometer, varying electric fields within the drift cell to constrain the plurality of ions as they get separated in the drift cell and thereby restrict axial diffusion of the plurality of ions in the drift cell.
