   In Fig. 2a, where the aqueous phase was used as the mobile phase and HCl as the eluter, the alkaloids were eluted as HCl salts, while in Fig. 2b, where the organic phase is used as mobile phase and triethylamine as the eluter, the alkaloids were eluted as free bases.

   pH-Zone-refining CCC uses a set of reagents (i.e., a retainer in the stationary phase and an eluter in the mobile phase). For the separation of acidic solutes, TFA is most often used as the retainer acid and NH₃ as the eluter base. For basic samples, triethylamine is used as the retainer base and HCL as the eluter acid.
