Figure 7: A cross-plot of ethanol adsorption isotherms (millimoles per gram unmodified versus millimoles per gram DMDCS-modified) for unmodified CPG-10 against DMDCS-modified CPG-10 to reveal changes occurring. It shows the gradual multilayer adsorption increase (small slope) followed by a jump during capillary condensation (bigger slope), on the modified sample.
