Analytical EquipmentINFRARED FOURIER SPECTROMETERInfraLUM FT-08 DETERMINATION OF FATTY ACID METHYL ESTER (FAME)CONTENT INDIESEL FUEL OR DOMESTIC HEATING FUEL BY mid-IR SPECTROSCOPY EN 14078：2014 INTRODUCTION Presence of fatty acid ethyl esters (FAME) in diesel fuel or domestic heating fuel (both hereinafter referred toas diesel fuel) is a signal of blending with biodiesel. The control of FAME content in diesel fuel is an essentialand actual task because of the need of the right fuel identification and registration of possible FAME impacton engines and fuel systems. To control the compliance one of the most accurate， rapid and simple methodsis EN 14078：2014. Lumex Instruments provides user-friendly analytical solution for EN 14078：2014 implementation using FTIRspectrometer InfraLUM FT-08 and powerful SpectraLUM software package. FAME content can also be measured by InfraLUM FT-08 in accordance withother standardl methods(ASTM D7371-14etc). Thesemeasurementprocedures are not given in the application. MEASUREMENT METHOD The method is based on measuring the transmission spectra of a sample ofdiesel fuel in the mid-IR spectral range. Consequent calculation of the FAMEconcentrationis performed byInfraLUMsoftware automatically bbycomparison of peak height against a calibration curve. MEASUREMENT RANGE Measurement range，%(V/V) Directives & standards for fuels Max.FAME value. %(V/V) 0.05-50 Worldwide Fuel Charter (5th ed.， 2013) <5 ISO 8217：2017 Petroleum products - Fuels (class F)-Specifications of marine fuels <7 ASTM D975-17aStandard specification for diesel fuel oils <5 Directive 2009/30/EC Fuel Quality Directive <7 EN 590：2013 Automotive fuels. Diesel. Requirements andtest methods <7 CAN/CGSB-3.517-2017 Diesel fuel <1 GB 19147-2016 Automobile diesel fuels <1 MEASUREMENT PROCEDURES The sample of diesel fuel is injected into the cell and the IR transmission spectrum of the solution ismeasured at around between 1670 cm" and 1820 cm， where FAME has strong absorption at 1745±5 cmdue to the ester carbonyl bond and where fossil diesel is transparent. Then the volume content of FAME inthe sample is calculated using the preliminary prepared calibration. EN 590 compatible analysis protocolcould be printed in one click.
