Detailed FTIR Analysis

IR spectrum of a typtical fuel measured with ERASPEC

ERASPEC uses a patented rugged Fourier transform infrared (FTIR) spectrometer to deliver laboratory precision in a portable instrument. At the single push of a button it analyzes your fuel for over 40 parameters within seconds. ERASPEC directly measures the significant gasoline components, such as aromatics, oxygenates and octane boosters. In addition, it determines all important gasoline parameters. Those include RON, MON, AKI, RVPE, VLI and distillation properties to name but a few.

In Diesel fuel the instrument directly measures total aromatics, polynuclear aromatics and the cetane improver 2-EHN. Biodiesel measurements deliver results for the FAME and FAEE concentrations. The instrument then uses the measurements to calculate the cetane number, cetane index and the distillation fractions. Jet fuel analysis additionally gives results for the freezing, flash- and smoke points.

The built-in oscillating U-tube density meter (ASTM D7777, ISO 15212) accurately measures fuel density and allows displaying the results in Vol% as well as in Mass%.

Huge Expandable Database

ERASPEC comes preconfigured with a huge database of several hundred international calibration samples. But we would not let this be your limit. Therefore, we made it easy to drive ERASPEC’s excellent result accuracy even further: It is possible to add as many samples of known concentrations or properties to the database as are required. By training ERASPEC with new samples you can even define completely new parameters for the results. This process is so simple, you should really give it a try.

Compliant Biodiesel Testing

Comparison of Diesel spectra with and without FAME measured with ERASPEC

Due to governmental regulations as well as influences on Diesel fuel properties it is important to monitor Biodiesel concentrations in Diesel blends. ERASPEC analyzes Biodiesel across a range of 0-65 Vol%, which covers all blend ratios in practical use.

It fully complies with the brand new ASTM D7806 standard and can also directly determine Biodiesel according to EN 14078. ERASPEC analyzes the sample for contaminations with vegetable oil and displays a notification if vegetable oil is detected.

ERASPEC is calibrated with a matrix of Biodiesel produced from canola oil. To increase the measurement accuracy even further, it offers a simple functionality to add additional calibration models for Biodiesel produced from other sources, such as soybeans.

ERASPEC fuel analyzer with installed auto sampler

Autosampler for Unattended Analysis

The 10-position autosampler lets you maximize your sample throughput while saving precious operator time. The sampler is directly attached and performs measurements without operator intervention.

Optimized Design for Unmatched Precision

Gasoline and Diesel/jet fuels show highly different IR signal intensities in measurements. To achievehighest precision for all fuel types ERASPEC uses a patented, purpose-designed dual transmission cell setup. Gasoline, which exhibits higher signal intensities, is measured through a 20µm cell whereas Diesel and jet fuel measurements are performed with a 100µm cell to enhance their low signal intensity.

High-precision measurements require the best signal-to-noise ratio to accurately determine concentrations of individual compounds. ERASPEC therefore uses an optimized spectral resolution of 4cm-1 for low-noise fuel measurements in full compliance with latest standards. Additionally, ERASPEC automatically chooses between different signals obtained from one substance and always uses the best signal of each component for evaluation. These features combined result in a superior signal-to-noise ratio and a truly comprehensive measurement range.
