In this paper we present the results of the ion mobility measurements made in pure isobutane (iC(4)H(10)) and in mixtures with argon (Ar-iC(4)H(10)) for a total pressure of 8 Torr (10.6 mbar) and for low reduced electric fields in the 10 Td to 45 Td range (2.4-10.8 kV.cm(-1).bar(-1)), at room temperature. The reduced mobilities, obtained from the peak centroid of the time-of-arrival spectra, are presented for Ar concentrations in the 5%-95% range.
