Determination of the non-constant component of the ion mobility using the spectrometer of ion mobility increment.
A new method for determination of the non-constant component, alpha(E), of an ion mobility, k(E), is suggested. The method uses the relationship U(C) (US) that can be experimentally obtained with a spectrometer of ion mobility increment with planar drift chamber. (UC is a compensating voltage, U(S) is separating voltage amplitude.) A general equation for alpha(E) has been derived. We have explored the possibility of determination of alpha(E) from the experimental data for different types of US(t). In two specific cases, analytical solutions have been obtained.
