Abstract

The influence of the carrier gas on vapor pressure (psat) measurements by the gas saturation method was studied. Eicosane (C20H42) was used as the test compound. Helium (He), nitrogen (N2), carbon dioxide (CO2), and sulfur hexafluoride (SF6) were chosen as the carrier gases. The apparent psat of eicosane was determined repeatedly in each of the four carrier gases at 323.15 K, and was found to increase with carrier gas in the order He
