Methods

gas chromatograph - enlarged view

Gas chromatography
Gas outflow from the cell is separated and quantified by gas chromatography (GC), enabling precise quantification for Faradaic efficiency determinations. Products measured include carbon monoxide, hydrogen, oxygen, methane, ethylene, and other gaseous hydrocarbons.
A separate autosampler channel allows automated sampling of liquid vials for volatile liquids determination (alcohols, aldehydes).

Fume hood
A tall fume hood equipped with carbon monoxide sensors allows experiments in CO reduction.
