Catalyst characterisation analysers
Both of the Quantachrome Instruments catalyst characterisation units, the Autosorb-1C-TCD and the ChemBET-3000, feature stable, oxidation-resistant detectors for characterising carbon contents
Both of the Quantachrome Instruments catalyst characterisation units, the Autosorb-1C-TCD and the ChemBET-3000, feature stable, oxidation-resistant detectors. These are an essential feature of the analysis type known as temperature programmed oxidation, or TPO, wherein materials containing various types of carbon are characterised by heating in normal air or diluted air (reduced oxygen content). Whilst the sample is expected to react, the detector (known as a thermal conductivity detector, or TCD) must not, but shall retain sensitive response to changes in gas composition! Both instruments have already been used to characterise diesel soot and are expected to play an increasing role in the development of commercial catalysts used for reducing emissions from diesel engines.
The Quantachrome Autosorb-1C-TCD.
In addition to TPO it is capable of performing temperature programmed reduction (TPR), temperature programmed desorption (TPD), metal area and dispersion measurements, BET surface area and detailed pore size analyses.
The Quantachrome ChemBET 3000.
This analyser represents affordable bench-top catalyst characterisation.
In addition to TPO it is capable of performing temperature programmed reduction (TPR), temperature programmed desorption (TPD), metal area and dispersion measurements and BET surface area.
Please see the website for further details of both devices.
