Fig. 1 — Overloaded elution profiles recorded for the same samples using two different columns: a Atlantis T3 C₁₈ and b XSelect CSH C₁₈. The mobile phase was acetonitrile/water with 2.6 mM TFA in gradient elution (10–25% acetonitrile in 10 min); 40 µL of MetEnk (4.4 mM) and LeuEnk (6.7 mM) were injected individually and the chromatograms overlaid. Note the considerably reduced tailing on the CSH column as compared to the T3 column
