advantage of mixed-mode columns in this respect is their higher loadability forionized samples. Finally, mixed-mode columns are virtually unique in being able tosimultaneously separate mixtures of anions, cations, zwitterions, and neutrals [73].A mixed-mode cation-[r]

our “choice” to fit the observed, inherently asymmetric line pro-files of the out-of-plane bending modes with symmetric cal-culated profiles forces us to adopt a somewhat small intrinsicline profile. We will assess the effect of these assumptions onour fitting results later on.[r]

7.4.3 Special ProblemsThe separation of ionic samples by IPC is subject to some of the same requirementsas for RPC:• a need for the close control of mobile-phase pH in some cases (e.g., ±0.10units or better)• a need for reproducible temperature contro[r]
