An operando FTIR reactor for studying materials and reaction mechanisms in real operating conditions.
Characteristics
Real-time conditions
Analysis of the gas and the surface phase using FTIR in real-time conditions to identify the nature of the reacted, intermediate and formed species.
Controlled flow
Analysis in operando conditions: conditions in which the process conditions (flow composition, temperature and pressure) are controlled to be close to the reality.
Features
