BET Liquisorb
The BET Liquisorb Sorptometer uses water for its tests
Description
PMI's BET Liquisorb is a recent extension of the "classic" BET static nitrogen adsorption technique. The BET Liquisorb allows for the automated volumetric characterization of adsorption of the vapor of a liquid as a function of the increasing or decreasing partial pressure of the liquid vapor. This innovative instrument provides the user with a direct test of how a particular gas interacts with a solid, as a function of the temperature and concentration of the gas, and the temperature of the sample.
Principles of Operation
A recent extension of the classic BET technique now allows for the automated, volumetric characterization of adsorption of the vapor of a liquid as a function of increasing or decreasing partial pressures of the liquid vapor. Liquids used include water and other organic liquids such as benzene, hexane, and acetone.
Applications
PMI's BET Liquisorb is an invaluable tool in a wide range of industries including ceramic, catalyst, and pharmaceutical. Specific applications for the BET Liquisorb include evaluating how quickly building materials will deteriorate based on their adsorption properties, properties of nonwovens such as moisture vapor transmission and adsorption, and properties of ceramics, including repulsion and adsorption.
