The MINISCAN IRXpert analyzer from AMETEK Grabner Instruments is a completely portable multi-fuel analyzer for gasoline, diesel and biodiesel blends that incorporates the advantages of mid-IR and near-IR spectroscopy to achieve enhanced accuracy of fuel properties. The instrument is an intelligent, self-learning analyzer that uses more than 12,000 data points from the infrared spectrum to determine the concentration of molecules in a sample. The unit is able to yield from that spectrum a “fingerprint” of more than 40 important fuel properties. The analyzer performs compound analysis according to international standards (ASTM D5845 for oxygenates, ASTM D6277 and EN 238 for benzene and EN 14078 for biodiesel). Predictions for octane number, AKI and cetane number are based on ASTM D2699, 2700, 613, ISO 5163, 5164; distillation on ASTM D86 and ISO 3405; and vapor pressure on ASTM D6378, D5191, D323 and EN 13016. An integrated temperature-controlled density meter allows for direct determination of fuel density. The unit comes fully configured and ready for fuels testing. A color touchscreen facilities menu navigation and allows for in-depth spectrum analysis. USB and Ethernet interfaces facilitate quick data transfer, printing, LIMS integration and remote control and service. The analyzer is highly adaptable and intelligent. An unlimited number of new parameters can be added with the push of a button. Users simply upload a database, and the analyzer creates the optimum measuring model.
