Chromatographic Methods of Analysis for Methanol and Ethanol in Automotive Exhaust 790690

A gas-liquid chromatographic system designed for analysis of methanol in exhaust from methanol/gasoline fueled vehicles is described. Modifications of this system for liquid analysis of methanol in gasoline, and analysis of ethanol in exhaust from ethanol/gasoline fueled vehicles are also discussed. Some results for methanol in exhaust from neat methanol and methanol/ gasoline fueled vehicles are presented, and are compared to emissions measured by a total hydrocarbon analyzer using flame ionization detection.
