Spectral Fuel Analysis in Seconds
ERASPEC is eralytics industry-proven multi-fuel analyzer with several thousand installations worldwide. It offers measurements of fuel component concentrations, complex properties like RON or cetane number, and density for gasoline, diesel oil , jet fuel and even specialized fuels like ethanol fuels. A single push of a button delivers all results within 1 minute.

FTIR Fuel Analysis
In FTIR fuel analysis a spectrum of the analyzed fuel is recorded within the mid-infrared region using a Fourier transform spectrometer. Counting on the chosen method a single measurement is in a position to detect over 40 parameters within a couple of seconds. For gasoline measurements e.g. RON, MON, AKI, distillation properties, esters and aromatics concentrations are determined. When analyzing diesel aromatics, cetane improvers, biodiesel and plenty of more are often quantified. Analyzing biodiesel ERASPEC distinguishes between FAME / FAEE and oil. It measures FAME fully compliance with ASTM D7806 and EN 14078. Typical parameters for jet fuel include FAME, aromatics, freezing and flash point, smoke point and distillation parameter, as well as viscosity.

Integrated ASTM D4052 Density Measurement
ERASPEC is again expanding the horizon of portable fuel testing with eralytics integrated state-of the-art temperature-controlled U-tube density meter modules DENS7777 and DENS4052. Together with the ultra-light density meter module DENS4052 (patent pending), offering density measurements fully compliance with ASTM D4052 & ISO 12185 (r = 0.0001 g/cm3), ERASPEC can measure density, benzene and FAME fully compliance with international fuel specifications, like ASTM D4814, EN228 and EN590. In its standard version ERASPEC is now equipped with eralytics new DENS7777 U-tube density module that's also temperature-controlled and measures fully compliance with ASTM D7777 & ISO 15212 (r = 0.0005 g/cm3).

Patented Design
The heart of the ERASPEC fuel analyzer may be a patented corner-cube retro-reflector FTIR spectrometer. For highest precision its laser and temperature controlled and its spectral resolution is ready-made to the task of fuel analysis. This reduces any noise to an absolute minimum, increasing the repeatability and lowering the possible limits of detection. ERASPECS’ unique triple cell design is now the quality for all analyzers making future instrument upgrades extremely easy. ERASPEC automatically selects between a 20 µm and a 100 µm path length measurement cell counting on the fuel analyzed. This enables ERASPEC to always deliver the simplest measurement result. A 3rd cell is employed to run background measurements if needed. For special applications (e.g. advanced cetane improver determination) a singular fourfold-cell design with wider path-length is out there.

Measurement Procedure
To perform spectral analysis with the ERASPEC fuel analyzer are often wiped out 4 simple steps:

Enter sample ID and operator name
Select the measurement standard and therefore the library to be used for calculating properties Put your sample next to the fuel analyzer and insert the inlet tube Press the RUN button

The measurement steps are visualized on the display, showing the deflection of the moving mirror of the interferometer. When the measurement is completed the results are displayed and may be printed or added to a library with one click. When adding the results of the fuel analyzer to a library an editor for entering known properties will appear. This may improve the standard of future measurements using the ERASPEC fuel analyzer, because the library are often tailored to a selected application.
