Micromeritics 3Flex Surface and Catalyst Analyzer w/ Smart VacPrep Sample Degasser

Description

Micromeritics 3Flex Surface and Catalyst Characterization Analyzer is a fully automated, three-station instrument designed for a variety of analyses with superior accuracy, resolution, and data reduction such as surface area, mesopore, micropore, static chemisorption, dynamic chemisorption, and vapor adsorption. With the chemisorption option, the 3Flex is configured to perform chemical adsorption analyses that enable the researcher to obtain valuable information about the physical or chemical properties of catalysts, catalyst supports, and a variety of other materials. With the addition of the integral thermal conductivity detector (TCD), dynamic chemisorption analyses are available to perform temperature-programmed reduction (TPR), oxidation (TPO), desorption (TPD), and reactions (TPRx). The TCD option provides the capability to investigate the temperature dependence of specific adsorption or desorption process profiles for catalyst and adsorbents, as well as pulse chemisorption in one instrument.

Available Physical Adsorptive

Nitrogen (N2), Helium (He), Argon (Ar), Krypton (Kr), Water (H2O) Vapor

Available Chemical Adsorptive

Hydrogen (H2), 10% Hydrogen in Argon, 10% Oxygen in Helium, 10% Carbon Monoxide in Helium
