Alternative fuels—biodiesel and ethanol products—make up approximately four percent of global fuel consumption. These alternative fuels are typically blended into conventional petroleum fuels. However, biofuels present some unique challenges including biological growth and oxidative degradation during storage. Blended fuels containing biofuels must also be tested to ensure they meet diesel engine operating parameters.
You can confidently determine ethanol purity and detect biodiesel contaminants using Agilent analyzers, which are configured based on ASTM standard methods. For fieldwork, you can rely on Agilent portable systems—including the Agilent 490 or 990 Micro GC biogas analyzer, the Agilent 4500 Portable FTIR, and the Agilent 5500 Compact FTIR. Trace metal impurities can be determined using ICP-MS, while elements be measured accurately using MP-AES.
