HER/CO stripping

  • 100% analyte collection efficiency allows accurate reaction product quantification
  • Gas dosing with reactant gases. The system allows to control the gas saturation of the electrolyte and study the effect of different gases on electrodes. Electrolyte saturation is obtained in just a click and avoiding the need of bubbling gas in external reservoirs for long time.

Isotope-labelling mechanistic studies

  • High-resolution mass spectrometry combined with isotope-labelled electrolytes enable unravelling reaction mechanisms
  • Standardized sample holder provides a flexible platform to study any bulk or nanostructured electrode. The instrument mounts standard off-the-shelf disk inserts from PINE (link). Custom nanoparticle electrodes can be e.g. sputtered or cast on glassy carbon disk inserts.

Propene oxidation

  • High sensitivity to a vast range of electrochemical products including high hydrocarbons, released in minute amounts.
  • Reaction mechanisms are investigated by isotope-labelled studies

Carbon monoxide reduction

  • Single turnover sensitivity. Each molecule produced on the electrode is collected into the MS, so the total production can be easily quantified. Notably, while the EC signal is drowned in capacitance immediately after the change of potential, the MS signal provides unique insight into the transient behavior at the electrode surface.
  • Quantification. The signals are quantified in pmol/s.
  • Product detection. The instrument can easily measure CO reduction products, including multi-C products such as ethylene, ethanol, propene, etc.
  • Real-time measurement. The methane release lasts only a few seconds. The high time resolution together with the high sensitivity of the system allow to measure fast transient phenomena in a fully quantitative fashion.
