The ASAP 2020 Chemisorption instrument can be used for many different analyses. One of the uses of the 2020 can be to analyze the chemisorption of hydrogen onto supported metal catalysts. In this study, 5 weight % palladium on activated carbon was used. During chemisorption, the bonds between H2 molecules dissociate on the metal and the individual hydrogen atoms chemically bond to the surface atoms of the palladium1. As the hydrogen bonds to the surface of the metal, the 2020 measures the quantity of hydrogen adsorbed at certain pressures. In this study, a wide range of pressures were employed, ranging from 0.01 mmHg to 500 mmHg.
