Exploring the effect of mesopore size reduction on the column performance of silica-based open tubular capillary columns

•Layer thickness in PLOT columns can be tuned, independently of HT conditions.•Reduction of mesopore size increases specific surface area, as physically expected.•Reducing mesopore size enhances phase ratio while keeping column efficiency.•Golay-Aris theory can support the experimental data on PLOT...
