Abstract
The invention provides improvements in a system for carrying out volumetric sorption analysis of porous materials. According to one aspect of the invention, the saturation pressure of the adsorbate gas is measured after dosing of the sample during an actual run has brought the adsorbate gas to a saturation condition above the sample, and this measured saturation pressure is then used by the system to determine the relative pressures at which data will be taken during desorption. In accordance with another aspect of the invention, the system automatically adds extra adsorbate gas to the dosing manifold until the analysis proceeds beyond a selected relative pressure, so that far fewer doses are required to reach initial target relative pressures in the case of materials which adsorb large amounts of gas at low relative pressures.
