Reducing our dependence on fossil fuels and our reliance on oil and petroleum supplies are worldwide issues. Many see the increasing use of biodiesel fuel as a key initiative to meet these global needs.
The move to include proportions of biodiesel in everyday fuel has created a host of unresolved issues for both engine manufacturers and diesel consumers. Uppermost among these are questions concerning the concentration of the biofuel (Fatty Acid, Methyl Ester – FAME) and its quality. This application note describes how infrared transmission measurements can be used to address the concentration measurements.
Detecting gases at low concentrations with FT-IR requires long pathlengths to increase absorption. The conventional approach employs a multi-pass White Cell where the light beam is reflected between two mirrors that are angled so that the beam emerges past one of the mirrors after a number of reflections, giving pathlengths up to tens of meters. In cavity-enhanced measurements, a highly collumated beat is reflected between two mirrors.
The ability to accurately characterize textile fibres is important in many fields, including textile conservation, forensic analysis and industrial production. Conventional methods such as microscopy and spectroscopy can be used to investigate the morphology and chemistry of a sample, but reveal little about its miscrostructure.
, The PerkinElmer Frontier or Spectrum Two series of FT-IR spectrometers can be utilized successfully for the determination of oil and grease in water samples. The method shows good linearity and precision, with a detection limit below 0.5 mg/L.
The FT-IR spectrum of biodiesel takes only a few seconds to measure with a diamond ATR accessory, and contains readily, accessible information about the extent of unsaturation in the fatty acid chains.
The need for sustainable fuel sources has led to an increasing global emphasis on fuels produced from renewable, biological sources. Biodiesel is one such fuel, and consists of fatty acid methyl esters (FAME) produced from vegetable oils or animal fats.
Heated ATR is used to follow the thermal changes in chcolatate, which is largely a suspension of sucrose and cocoa solids in a matrix of cocoa butter.

As the importance of sustainable energy production increases, so too does the global commitment to using fuels from renewable biological sources. This article discusses the use of FT-IR spectroscopy for quantification of FAME in fuels, and compares the two current standard test methods, EN 14078 and ASTM D7371, considering their relative merits for both blend and trace analysis.
