Ikey in-situ XRD Reaction Cell

The Ikey in-situ XRD reaction cell is a capillary plug flow reactor suited for controlled-environment studies (allowing research to dictate the environment) of engineering materials and heterogenous catalysts. The x-ray flow reactor easily mounts directly into most commercial x-ray diffraction instruments and may be controlled via diffractometer integration or via a Universal Controller also supplied by Cape Catalytix.
The device’s proprietary fitting allows access to full industrial conditions (up to 20 bar and 450 degrees) without the need for specialists tools. The x-ray in situ reactor allows for continuous catalyst structural property monitoring as a function of reaction environment (T, P, gas composition and space velocity) and which, when coupled with off-gas analysis (gas chromatography, mass spectrometry, etc.), provides for a fully operando structural property characterization methodology.

Advantages over commercially available in-situ cells include minimised dead volume, defined flow path, Direct in-sample temperature measurements and the possibility of co-feeding gases such as water vapour.
The newly designed in-situ cell uses a capillary tube (75mm long and outer diameter of 1-2mm) as the reaction vessel. The first-of-its-kind design suitable even for kinetic studies. The choice of capillaries (polyimides, borosilicate and quartz) permits access to broad range of applications and chemistries not readily achievable in other cells.
