Chemisorption Analysis Carbon Monoxide Chemisorption Hydrogen Chemisorption Chemisorption is particularly suited to the analysis of catalytic materials. Common adsorptives are carbon monoxide and hydrogen and results are tailored to specific samples according to the active constituents and their respective loading . Key Information: Static Chemisorption Analysis Dynamic / Pulse Chemisorption Analysis Metal Dispersion (%)        Metallic Surface Area of Sample Metallic Surface Area of Metal      Crystallite Size (nm)       Langmuir Surface Area of Sample                                             Freundlich isotherm plot                                              Temkin isotherm plot Chemisorption analysis can be further extended to show the difference between strong and weak chemisorption. An alternative analysis is the measurement of the surface acidity of a material using ammonia adsorption and is particularly applicable to the understanding of zeolite samples. Preparation of the sample prior to analysis is undertaken in-situ on the instrument, thereby ensuring the elimination of any contamination. Preparation can be undertaken with a high degree of control over temperature and temperature ramp rate. Temperatures of up to 1100 °C can be reached and vacuum levels of 10-7 mmHg achieved.
