Figure 7. GC experiment for comparison of xylene-selectivity.

a) GC chromatogram of the supernatant solutions recorded at the specified time intervals in the setup A (Quaternary xylene mixture immersion test). Highlighted signals denote the mixed signal for the combined contributions of both MX and PX, intensity of which is getting steadily diminished with increasing time of immersion with MOF, b) GC chromatogram of the supernatant solutions recorded at the specified time intervals in the setup B (Ternary xylene mixture immersion test; excluding PX). Highlighted signals denote the individual signal for the contribution of MX only, intensity of which is remaining unchanged with increasing time of immersion with MOF, c) GC chromatogram of the supernatant solutions recorded at the specified time intervals in the setup C (Ternary xylene mixture immersion test; excluding MX). Highlighted signals denote the individual signal for the contribution of PX only, intensity of which is getting steadily diminished with increasing time of immersion with MOF.
