Establishing Sample Degassing Conditions for the FlowSorb

Sample preparation is crucial in obtaining reliable, repeatable results with the FlowSorb just as it is with all physical adsorption instruments. Users typically establish the temperature-time parameter that gives consistent results by heating samples of the material to be analyzed to various temperatures for different times and then measuring surface areas, or they merely choose […]

Acid Site Characterization of NH4+ ZSM-5 (SiO2/ Al2O3:280/1): A Pulse Chemisorption and TPD Application for the AutoChem

The Brønstead acidity of zeolites and other catalysts is of keen interest, as this affects the kinetics of reactions. Characterization of these sites is consequently very important and is often performed according to the ASTM D 4824 ammonia chemisorption method. An alternative, but comparable, characterization method involves pulse chemisorption of propylamines followed by a temperature-programmed […]
