“…It is due to higher dissolution of carbon dioxide in alcohol at lower temperatures. Sih et al [11,17] have also measured the gas expanded liquid viscosity for (carbon dioxide + methanol) and (carbon dioxide + ethanol) systems at 303.15 K using a customised falling-weight viscometer; these data were also presented in this figure. As on can see, the measured viscosity data are consistent with Sih et al [11,17] measurements.…”

Maximizing kinetic performance in supercritical fluid chromatography using state-of-the-art instruments

“…Then, viscosity was predicted for different CO 2 and MeOH mixtures using a correlation of second order between viscosity and MeOH content, on the basis of experimentally determined data published by Sih et al [32]:…”

Evaluation of stationary phases packed with superficially porous particles for the analysis of pharmaceutical compounds using supercritical fluid chromatography

“…P was corrected for the native system pressure drop determined without a column in place. Estimation of supercritical CO 2 viscosity was made on the correlations proposed by Ouyang [43] and applied to different CO 2 /methanol mixtures using a second order correlation between viscosity and MeOH concentration, based on previously published experimentally-determined data [44]. By combining these two correlations, the viscosity of mixtures of supercritical CO 2 and MeOH for a given pressure and temperature can easily be predicted.…”
