Concatenated gas saturation vapor pressure apparatus

Abstract

This article presents a gas saturation vapor pressure apparatus capable of simultaneous vapor pressure measurements on a total of up to six samples. The apparatus operates at 280–365 K and total pressures of 100–200 kPa. The apparatus features a series of alternating saturators and adsorbers allowing multiple vapor pressure measurements to be made with a single carrier gas stream. Total carrier gas flow is derived from mass measurements. The apparatus provides multiple simultaneous vapor pressure measurements for series or families of compounds allowing correlations of physical properties within the families.
