A system for catalyst characterisation, kinetic and thermodynamic measurements

Hiden Analytical is an industry-leading supplier of microreactors and mass spectrometer systems for complex areas of research, including catalyst characterization, screening, and reaction studies. With rapid responses for kinetic and thermodynamic measurements at temperatures of up to 1000°C (1832°F), Hiden’s modular microreactor and mass spectrometer systems are a unique solution for analytical challenges specific to the industry.

HPR-60-MBMS, A system for analysis of neutrals, radicals and ions


The CATLAB is a modular system designed as a complete solution from a single manufacturer, providing optimal analysis through seamless hardware-software integration. Using a low thermal mass furnace with built-in air cooling, the CATLAB microreactor can reach maximum temperatures with a heating ramp range of 1-20°C/min. An in-bed (type K) thermocouple can then provide direct sample measurement with an accuracy of within a single degree, offering ultra-precise thermodynamic insights for reaction studies and catalysis. Yet this is only one half of the modular system.

Using a quartz inlet capillary (QIC) species probe, the dedicated mass spectrometer system can acquire two, four, or eight individual gas streams or a combined vapor manifold with independent mass flow control at flow rates of 3 – 100 ml/min. This combination allows for mutual kinetic and thermodynamic observation with the real-time acquisition of data for subsequent digital analysis.
