WebCyclic ion mobility has a unique circular path, which enables you to define your path length by simply performing multi-pass experiments. Ions of a given mobility range can be selected and passed around the device as many times as you need, allowing you to ‘zoom in’ on analytes of interest. Cyclic Ion Mobility Device
