Fig. 8 — Effect of the stationary phase and buffer on full equilibration. Stationary phase and buffer combinations of SB-C₁₈ and TFA (), SB-C₁₈ and TEAP (), XDB-C₁₈ and TFA () and SB-C₁₈ and TEAP () were used were TFA and TEAP represents a 0.1 % (v/v) TFA or 50 mM TEAP at pH = 2.0 buffer in the eluent, respectively. Other conditions are described in Fig. 2.
