The effect of a few key instrumental control parameters on the instrumental analysis of coconut fatty acid methyl esters (FAME) compounds in coconut B20 biodiesel using gas chromatography-mass spectrometry (GC-MS) is presented here for the instrumental analysis laboratory course. FAME compounds are some of the most common non-polar long chain hydrocarbon compounds with a polar methyl ester group that are found in petroleum products, such as biodiesel, where they tend to often be greater in concentration than other long chain hydrocarbons. FAME compounds are considered to be a renewable resource under the Energy Policy Act (EPAct) of 2005 and the Energy Independence and Security Act (EISAct) of 2007, where they are primarily derived from plant based feedstocks for the production of alternative fuels such as biodiesel. For the integration GC-MS techniques into the instrumental analysis laboratory course this article works to describe an experimental approach to educators. GC-MS, while universally applicable, has just begun to be integrated into undergraduate instruction as a didactic tool for the analysis of organic compounds utilizing the standard practice of target and qualifying ions. Moreover, this article works to inspire educators to use modern GC-MS instrumental analysis techniques, which are typically viewed as a daunting undertaking due to the overabundance of instrumentation parameter settings available, to encourage undergraduate students to qualitatively investigate the effect of a few key parameters on the instrumental analysis of an environmentally relevant topic.
