Catalyst characterization units feature stable, oxidation-resistant detectors which are an essential feature of the analysis type known as temperature programmed oxidation, or TPO
Both of Quantachrome Instruments's catalyst characterization 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 characterized by heating in normal air or diluted air (reduced oxygen content).
While 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 characterize diesel soot and are expected to play an increasing role in the development of commercial catalysts used for reducing emissions from diesel engines.
Autosorb-1C-TCD Quantachrome's Autosorb analyzer represents state-of-the-art in automated catalyst characterization.
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.
Chembet 3000.
Quantachrome's Chembet analyzer represents affordable bench-top catalyst characterization.
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.
