Micro Reactors
Rapid catalyst screening reactors
These µ-Reactors are easily interfaced to the GC/MS system, allowing real-time monitoring of the chemical species generated by vapor phase contact reaction with a catalyst.

Two types of reactors have been developed to facilitate the rapid characterization of catalysts. Both reactors are designed to heat and cool rapidly which increases the number of catalysts that can be characterized in a given period of time. Three different reaction gases can be connected to the system so that each catalyst can be evaluated under a variety of reaction conditions.
- Single µ-Reactor (RX-3050SR): The Single µ-Reactor has a quick-change catalyst reaction tube. Only liquids or gases can be introduced. The temperature of the reactor can be programmed through a variety of heating modes such as isothermal, linear and stepwise temperature program.
- Tandem µ-Reactor (RX-3050TR): The Tandem µ-Reactor consists of two reactors, connected in series. The first reactor is used to preheat a gaseous sample, vaporize a liquid sample, or pyrolyze a solid sample. The first reactor operates at a constant temperature. The volatiles exit the first reactor and reach the second reactor. The second reactor is build up like the Single µ-Reactor. Heating and analysis modes of the reactor are also the same as those of the Single µ-Reactor. The software enables isothermal, linear and stepwise temperature programs.
