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 fuel, jet fuel and even specialized fuels like ethanol fuels.
Our latest feature for the analyzer eraspec is our new NIR/PLS module. The NIR/PLS module extends the spectral range of eraspec to the NIR range (4000–4500 cm -1) by taking an additional measurement through a 500 μm measuring cell. In this range, so-called combination bands show absorption, enabling the distribution of alkanes to be determined that significantly influence important fuel properties. Combining this NIR information with eraspec’s standard MIR data within eralytics innovative PLS model improves the SEC for RON and MON by a factor of 2.
