The gravimetric jet fuel total oxidation tester (JFTOT) was developed several years ago to provide JFTOT conditions which measure quantitatively the solid/deposit products formed in aviation fuels. The gravimetric JFTOT has now been used to measure these products in a small set of typical diesel fuels. ERASPEC - Spectral Fuel Analysis in Seconds. It’s all about pushing a button: ERASPEC is the leading fully automated mid FTIR Spectrometer for multi-fuel analysis. Gasoline, diesel, jet fuel and biofuels are measured within 60 seconds.
The total scope of FTIR applications is extensive. Some of the more common applications are: As an example, numerous components on automobiles are ideal for FTIR analysis: epoxies, oil coatings on parts, fuel, rubber seals and o-rings, tires, paints, fabrics . Fourier-transform infrared spectroscopy (FTIR) is a technique used to obtain an infrared spectrum of absorption or emission of a solid, liquid or gas. An FTIR spectrometer simultaneously collects high-spectral-resolution data over a wide spectral range. This confers a significant advantage over a dispersive spectrometer, which measures intensity over a narrow range of wavelengths at a time.
Fourier Transform-Infrared Spectroscopy (FTIR) is an analytical technique used to identify organic (and in some cases inorganic) materials. This technique measures the absorption of infrared radiation by the sample material versus wavelength. The infrared absorption bands identify molecular components and . The application of principal component analysis by interval method (iPCA) made it possible to locate the best spectral intervals for the separation of samples of biodiesel using UATR-FTIR spectra data. In light of the results obtained in the FTIR, the SIMCA modeling allowed for the % classification of the soybean biodiesel by:

Analysis of fuel deposits. Modes for both bulk and surface analyses were desired. Although the absorption mode required relatively large quantles of deposit, it was selected for continued use because it was the only mode which provided bulk analyses.

Helmick, Gary T. Seng. Five modes of operat1on (absorpt1on, em1ssion, single reflectance, attenuated total reflectance, and photoacoust1c) of a N1colet Fourier Transform Infrared Spectrophotometer have been 1nvest1gated in order to determ1ne which modes were most su1table for qualitative analysis of jet fuel depos1ts.
Using primarily the absorption and emission modes, the effects of fuel type, stress temperature, stress time, type of spiking agent, spiking agent concentration, fuel flow, and post-depositional treatment on the chemical nature of fuel deposits have been determinedAuthor: L.

FTIR analysis and monitoring of synthetic aviation engine oils. Two-dimensional IR correlation analysis was employed to investigate and interpret observed trends in the spectra, as acid was formed and antioxidant species were depleted in the oils, as a function of aging and engine wear. the use of FTIR spectrometry to monitor fuel and Cited by: Fuel Thermal Oxidation Tester (JFTOT) is used to test the thermal oxidation stability of aviation fuel according to ASTM D It has been used by number of workers [5,8] to investigate IDID formation.
When used with diesel, the test fuel is passed over a heated metal test piece and can be thought to simulate fuel passing through a diesel. Biodiesel Analysis Increased use of Biodiesel.
Many countries allow or require biodiesel in regular diesel Some states allow up to 3% biodiesel in diesel without disclosure Biodiesel is not appropriate for all fuel uses Can clog filters, reduce cold weather performance, or cause problems with storage. Intelligent FTIR System for Efficient Fuel Analysis From the very beginnings of fuel characterisation, infrared spectroscopy was widely applied in the field of fuel analysis.
Fuel, be it gasoline, diesel or jet fuel, consists of a complex mixture of hydrocarbons of which many have no characteristic absorption in the IR. They constitute the. Is there any free software to not only view FTIR spectra but also save in other formats like ASCII. FTIR analysis of aviation fuel deposits.

FTIR spectroscopy offers a vast array of analytical opportunities in academic, analytical, QA/QC and forensic labs. Deeply ingrained in everything from simple compound identification to process and regulatory monitoring, FTIR covers a wide range of chemical applications, especially for polymers and organic compounds.
This standard specifies a rapid screening method using flow analysis by Fourier transform infrared (FA-FTIR) spectroscopy with partial least squares (PLS-1) processing for the determination of the fatty acid methyl ester (FAME) content of aviation turbine fuel (AVTUR), in the range of 10 to mg/kg.
The build-up of deposits in diesel fuel injectors has been known for many years. In the s, the build-up of deposits on the pintle of a fuel injector was reported by Montange et al . The development and introduction of fuel additives to reduce injector fouling subsequently followed .The theory behind FTIR analysis given here is general but the application examples only relevant for a combustion situation like boilers, furnaces, incinerators fires and for automobile exhaust measurements.
Typical for these applications are the presence of large quantities of water and carbon dioxide.
