Coefficient of Ion Mobility Versus Electric Field Strength Dependence in Gases: Experimental Determination

摘要

A technique for finding the electric field dependence of the coefficient of ion mobility in gases is suggested. For ions of 2,4,6-trinitrotoluene, 2,4-dinitrotoluene, 1,3,5-trinitrobenzene, 1,3-dinitrobenzene, and dimethylmethylophosphonate, these dependencies are taken in air by applying a variable periodic polarity-asymmetric specially shaped electric field. The accuracy of the technique suggested is estimated and compared with that of the conventional drift tube method.
