Portable Diesel Analysis with mid-FTIR
IROX Diesel is a Mid-FTIR analyzer dedicated to Diesel analysis: With a different spectrometer cell, its own on-board software and a vast calibration library handling is as easy as with the gasoline unit. This instrument also uses an improved calculation model, based on Cluster analysis and MLR for the determination of the key properties of diesel fuel such as Cetane Number, Cetane Index and Distillation Properties. Fast and easy on-site custom calibration can be achieved by adding a new sample in less than 4 minutes. An excellent spectral resolution ensures results with highest precision in less than 3 minutes. IROX DIESEL has been upgraded for a new application: the determination of the FAME (Biodiesel) content in Diesel Fuel (EN 14078).
IROX-Diesel has been upgraded to determine the content of mono-alkyl esters of long chain fatty acids (or FAME/Biodiesel) in a mixture with normal diesel fuel.
The revised method and software modifications also resulted in a significantly improved precision for the determination of the Cetane Improver, Polynuclear Aromatics (PAH), Cetane Number and Cetane Index: calculating the second derivative of the additional peaks of Cetane Improver and PAH resulted in measurement data with an increased accuracy compared to the official methods and better repeatability.
IROX DIESEL is factory calibrated for the determination of FAME (Biodiesel) in Diesel Fuel: depending on the concentration range, two typical absorption peaks in the IR-spectrum are used.
