Product Introduction

The PX-RC-DRS-A3 is designed for diffuse reflection studies in liquid–solid and gas–liquid–solid systems. It is compatible with mainstream FTIR and UV-visible spectrometers and can be equipped with a Raman dome for in situ Raman characterization. The cell supports experimental conditions from vacuum to high pressure and from room temperature to elevated temperature. Its extremely low internal reactive volume ensures an average gas residence time below 2 seconds, making it highly suitable for spectrodynamic and transient-response studies in multiphase catalysis.

Product Features

Multiphase Capability

Supports liquid–solid and gas–liquid–solid systems for realistic catalytic reaction environments.

Low Dead Volume

Enables transient spectroscopy tests such as SSITKA and MES in multiphase systems.

Broad Spectroscopic Integration

Compatible with FTIR, UV-Vis, and Raman spectrometers for comprehensive multiphase characterization.
