Figure 2-6. Langmuir isotherms of water adsorbed on two hydrosilated (Cogent Silica, Cogent Bidentate) and four silica gel (C-30 YMC carotenoid, YMC Triart Diol HILIC, zwitterionic sulfobetaine ZIC-HILIC, and TSkgel Amide 80) bonded stationary phases. c_m, volume fraction of water in the mobile phase in equilibrium with the stationary phase; c_s, volume fraction of excess water contained in the pores of the stationary phase. Based on unpublished data from J. Soukup, P. Jandera, P. Jana´s.
