Tandem µ-Reactor (Rx-3050TR)

On sale

A tandem reactor mounted on a GC for rapid qualitative and quantitative determination of catalytic reaction products by GC/MS.

The Tandem μ-Reactor was developed to rapidly screen laboratory-prepared catalysts. The reactor consists of a pyrolysis furnace and a catalytic reactor, and it can be directly connected to a gas chromatograph mass spectrometer (GC/MS) to observe real-time changes of the products formed by the gas-phase catalytic reaction between the sample and the catalyst.
In addition, it has a rapid heating and cooling function, and the catalyst reaction tube packed with the catalyst can be replaced within a few minutes, greatly improving the efficiency of catalyst screening. A flow controller is provided standard, allowing you to easily switch among three different reaction gases. Further, in combination with Selective Sampler and MicroJet Cryo-Trap options, automated analysis of products formed in up to eight temperature zones can be performed.

  • Features

  • Specifications

1. Catalysts screening with all sample forms
Catalyst reaction products can be monitored through online-MS analysis mode. Also, GC/MS analysis can be performed at desired reactor temperatures.

2. Micro-Reactors capable of rapid heating/cooling

The micro-Reactors feature with multi-linear temp. programs and multi-stepwise temp. programs (up to 8 steps). The ramp rate can be set from 1 ºC to maximum 200 ºC/min, while the temperature can be controlled from 40 ºC to 700 ºC.

3. Rapid switching of catalyst reaction tubes
Switching catalysts can be accomplished in a few minutes using the proprietary quartz reaction tube (i.d. 3 mm, o.d. 4 mm, length 78 mm).

4. In the Tandem µ-Reactor, two reactors (1st and 2nd), are individually temperature-controlled
The 1st Reactor (upper reactor) is used to preheat a gas, vaporize a liquid, or thermally decompose organic solids (biomass analysis) to generate gases. The catalyst reaction tube is packed with a catalyst and placed in the 2nd Reactor (lower reactor).

5. Two flow control options available
