FAIMS APPARATUS AND METHOD COMPRISING AN ION SEPARATION CHANNEL OF HELICAL SHAPE |
摘要 |
A method and apparatus for high resolution separation of ions based on their high field and low-field mobility properties is described. An elongate ion separation channel is defined by a plurality of channel walls. First and second channel walls have first and second spaced ion separation electrode assemblies (80, 90) respectively. A power supply applies a periodic asymmetric potential to one or both of the electrode assemblies (80, 90) so as to generate a periodically asymmetric electric field in the channel for ion mobility separation. The channel walls define an ion separation channel of substantially helical shape.
