Saturation of Ion Current and Discrimination Based on Focusing Strength

3 Saturation of Ion Current and Discrimination Based ON Focusing Strength 

Focusing of ions in curved FAIMS (4.3.1) means a pseudopotential bottoming near the gap median. Devices using such wells to guide or trap ions (e.g., quadrupole filters or traps and electrodynamic funnels) have finite charge capacity or saturation current (/sat) the Coulomb potential scales as the charge density squared and, above some density, exceeds the well depth and expels excess ions from the device.

The value of Eq also depends on the species and drops for those with more linear
