Coupled with a Chemisorption Analyzer
The integration of mass spectrometry with chemisorption analyzers combines precise control of gas adsorption and desorption (e.g., TPD and TPR) with real-time, high-sensitivity gas composition analysis. This powerful combination allows dynamic monitoring of gas species, concentration changes, and temperature-dependent behavior during reactions. The result is deeper insight into the distribution of active sites, reaction kinetics, and structure–property relationships on material.
Coupled with a Reactor System
The reactor system is a compact, high-efficiency setup that simulates real industrial reaction conditions with precise control. Coupled with the Master 400, it enables real-time detection of reaction products from microreactors. This provides insights into composition, reaction mechanisms, and kinetic behavior. It also supports catalyst evaluation and the development of new catalysts and reaction processes.
