ASTM® D4815
The ASTM® D4815 method is designed to monitor oxygenated compounds in gasoline at percentage concen- trations. The method described in this application note is intended to enable these analytes to be monitored down to low-ppm concentrations.
There is an increased need to monitor the level of oxygen- ates in reformulated gasoline because of the increased risk of contamination from more abundantly available biofuels. Gasoline contamination with oxygenated compounds can lead to more toxic carbonyl emissions into the atmosphere from engines running the fuel.
Contamination of feedstocks with oxygenated compounds can cause degradation of expensive catalysts and impact the refining process.
