Determination of of cations in denatured ethanol
A
Metrohm UK product story
Edited by the Manufacturingtalk editorial team
Nov 9, 2006
An article from Metrohm describes a simple ion chromatography methodology to determine a number of cations in pure 200 proof denatured ethanol.
The contamination of ethanol fuel with soluble metal ions such as lithium, sodium, ammonium, potassium, calcium, magnesium and other cations can affect engine performance since salts and sediments that precipitate can block the nozzles and cause corrosion in the vehicle components in contact with the fuel.
The article (LC-GC Application Notebook - September 2006) describes a simple ion chromatography methodology to determine a number of cations in pure 200 proof denatured ethanol.
A Metrohm 861 Advanced Compact IC equipped with conductivity detector and Metrohm Inline Matrix Elimination (MISP) technology is applied for this method.
