Surface Energy Analyzers/Inverse Gas Chromatograph RSS Feed - Surface Energy Analyzers/Inverse Gas Chromatograph

Surface energy analyzers or second generation inverse gas chromatographs are used to characterize particulates, fibres and thin-films. It is a gas phase technique used to determine a range of surface and bulk properties. It involves passing a constant concentration of gas through a column of solid material and the time taken for the concentration front to elute down the column is measured with a detector. A variety of physico-chemical properties can be determined by using a range of different gas probe molecules.

It is possible to simultaneously weigh two samples with the IsoSORP instruments. Along with determining the mass change of the sample material, a second inert sample can be weighed.
The IsoSORP® Manometric instrument is capable of determining gas adsorption and desorption of up to five samples using the static volumetric method.
The SA 3100 with automated dewar lift is a complete pore size and surface area anlysis system with integrated outgassing stations and vacuum pump and is highly accurate. It features continuous saturation pressure measurement, has a minimum manifold volume to enhance sensitivity, and performs a multipoint helium free space measurement, to improve repeatability and accuracy.
