Simplified biofuels measurements with portable mid infrared analyzers
Product quality begins at the production facility and extends to consumer filling station. Some process control or quality verification analyses can be done with quick and simple verification tests while others require more complete tests according to the ASTM or EN approved methods. Many crucial measurements can be performed by mid-infrared (IR) analysis. These measurements include free fatty acids and water in the incoming feedstock, total glycerin during transesterification in production, water in methanol and fuel blend ratios (biodiesel in diesel or ethanol in gasoline).
