Resolving catalyst responses using a low-volume DRIFTS reactor
2 Oct 2026Understanding how catalyst systems respond to changing reactant streams requires rapid gas switching and time-resolved measurement. However, excess reactor dead volume can obscure transient responses and limit mechanistic insight.
This application note from Specac investigates reactant-stream modulation using a low-volume, high-temperature DRIFTS reaction chamber. The study demonstrates rapid exchange of gas-phase species and tracks the evolution of reactants, surface-bound intermediates and products during heterogeneous catalytic reactions.
Explore how low-volume DRIFTS can support modulation excitation spectroscopy and transient catalyst characterization.
