Gaseous and liquid products made in gas phase thermal catalysis and electrochemical reactions are analysed during and after the reaction, to make product-selectivity measurements.

Gas Chromatography (GC)

Online analysis of gaseous products. GCs with different analyte detectors:

  • Agilent 7890A for gaseous product anaylsis and







  • Schimadzu GC-2010 Plus with auto-sampler attachment for liquid product analysis
    • Thermal Conductivity Detector (TCD), Flame Ionisation Detector (FID)

Liquid Product Gas Chromatography (Liquid Product-GC)

Liquid alcohol products in the electrolyte after the reaction are analysed (offline), with autosampler attachement for high throughput analysis.
