Ob. Rudakov et Vf. Selemenev, Refractive index of binary mobile phases for high-performance liquid chromatography, RUSS J PH C, 73(12), 1999, pp. 2019-2022
The refractive indices of some binary mobile phases for normal and reverse
phase high-performance liquid chromatography were examined as functions of
the volume fraction of the modifier. These dependences were described by pa
rabolic functions containing the refractive indices of the constituent comp
onents and only one empirical parameter. Deviations of the refractive indic
es of the mobile phases from the additivity rule were discussed.
