Experimental ion mobility measurements in Ne-CF₄

Abstract

In this paper we present the results of the ion mobility measurements made in gaseous mixtures of neon with carbon tetrafluoride (Ne-CF 4 ) at a total pressure 8 Torr (10.6 mbar) and for low reduced electric fields in the 10 to 25 Td range (2.4-6.1 kV•cm −1 •bar −1 ), at room temperature. The time-of-arrival spectra revealed only one peak, which was attributed to CF + 3 . The reduced mobilities obtained from the peak centroid of the time-of-arrival spectra are presented for Ne concentrations in the 5%-95% range.
