LA3234C - UL - RFT for Supply, Delivery, Installation, Commissioning and Calibration of an Electrochemical Mass Spectrometry System

Description du marché

The University of Limerick request the supply of an Electrochemical Mass Spectrometry System for the Quantitative Real-Time Detection of Volatile Electrochemical Reaction Products. The electrochemical mass spectrometry system should combine electrochemistry with mass spectrometry to enable highly sensitive time-resolved detection of volatile chemical species directly from a liquid electrolyte during electrochemical reactions. The electrochemical mass spectrometry system must be compatible with volatile electrolytes - both aqueous and non-aqueous - and its application scope includes hydrogen evolution reactions, oxygen evolution reactions, nitrogen reduction reactions, NOx - NO, NO2, N2O - electroreduction reactions and electrochemical CO2 reduction reactions. With this electrochemical mass spectrometry system, all volatile chemical species - such as H2, O2, CO, CO2, HCOOH, CH4, C2H2, C2H5OH, CO-NH2-2, NH3, N2H2, N2H4, NO, N2O4, N2O, NO2, CH4, C2H4, etc. - generated at the electrodes during these electrochemical reactions must be detected in situ and quantified completely from a liquid electrolyte. The system must have high sensitivity with a 100 percent detection efficiency of volatile chemical species for the mass spectrometry detector, and the measurement results must be highly reproducible. Additionally, isotope labeling experiments for investigating the electrochemical reaction pathways should also be adaptable to this system.
