A new Hiden Analytical HPR-40 DEMS (Differential Electrochemical Mass Spectrometry) system has been installed at the Department of Chemical Sciences of the University of Padua, in the laboratory of Professor Christian Durante.
Professor Durante’s research group focuses on electrocatalysis and applied electrochemistry, with particular emphasis on the development and mechanistic understanding of advanced catalysts for small molecule electrochemical transformations. The new instrument will support ongoing research into the electrochemical conversion of CO₂ into value-added products and sustainable fuels.
The system combines an electrochemical cell with a quadrupole mass spectrometer, enabling real-time detection of gaseous and volatile species produced during electrochemical reactions. This allows for direct correlation between electrochemical activity and product formation, providing essential insights into reaction mechanisms and catalyst performance.
The installed DEMS is equipped with a triple-filter quadrupole, ensuring high sensitivity, abundance stability and excellent contamination resistance. It also includes an upgrade for corrosive gas operation, allowing safe and reliable analysis of reactive or aggressive species commonly encountered in electrochemical environments.The laboratory deals with heterogeneous catalysis, with multidisciplinary and multiscale approaches for the design and optimization of innovative chemical processes. The instrument will be used mainly for research on CO₂ reactions via methanation reactions, reverse water gas shift and dry reforming of methane.
