Low‐Field NMR Relaxation Analysis of High‐Pressure Ethane Adsorption in Mesoporous Silicas

Interparticle or mesopore phenomenon? We demonstrate simple low-field (12.7 MHz) 1H NMR relaxation measurements as a quantitative tool with which to inform high-pressure hydrocarbon gas adsorption and liquefaction phenomena within a range of high surface area mesoporous silica materials with pore sizes between 6 nm and 50 nm.
