Ethanol fuel is a sustainable energy resource intended to provide a more environmentally and economically friendly alternative to fossil fuels. Ethanol fuel for automotive applications is becoming increasingly widespread and its market is continuing to grow. Measurement of ethanol was traditionally done with an impinger and a gas chromatograph (GC) system but this method is not a direct measurement, usually requires manual handling and takes a long time for post processing of data. The Innova photoacoustic analyzer can directly measure the ethanol emissions in vehicle exhaust without using the impinger/GC system. For the past eight years at Chrysler, the Innova has been used as a stand alone analyzer and the emission sample bags were physically transported to the chemistry lab for ethanol measurement. The data had to be manually entered and post processed for the final results.
