Gas analyzer Micromeritics ChemiSorb HTP

for quality controlchemisorptionflow

High throughput static manometric chemisorption analyzer Six independent analysis stations for chemisorption In-situ sample activation with independent temperature and flow control for each reactor Precise for research and development, high throughput for quality control applications The Micromeritics ChemiSorb HTP is a fully automated, high-throughput chemisorption analyzer for characterizing catalysts, metal-supported nanoparticles, and chemically active materials used in sensor applications. Six independent stations running parallel analyses reduce operator intervention and increase lab productivity. The ChemiSorb HTP is a static manometric chemisorption analyzer. Generally, two adsorption ‘isotherms’ (quantity of gas adsorbed as a function of pressure at constant temperature) are collected at sub-atmospheric pressures: the first representing total adsorption, the second representing reversible adsorption, and the difference between the two representing the irreversible adsorption (i.e. ‘chemisorption’). This technique provides information on the quantity of adsorption sites, from which subsequent calculations may be done for the percent metal dispersion, active metal surface area, size of active particles, and surface acidity of catalyst materials. Static chemisorption provides the highest level of detailed surface characterization, providing total chemisorption, irreversible (strong) chemisorption, and reversible (weak) chemisorption over the widest range of catalyst chemistries. Provides a stable isothermal process zone to eliminate condensation of vapors and provide long-term process stability
