Adsorption Isotherms<br />
An Adsorption Isotherm is obtained by measuring the<br />
amount of gas adsorbed across a wide range of<br />
relative pressures at a constant temperature (typically<br />
liquid N2, 77K). Conversely desorption Isotherms are<br />
achieved by measuring gas removed as pressure is<br />
reduced
