Ethanol Content in Gasoline Analyzer

Infracal 2 Biofuel Analyzers MEASURING PERCENT BIODIESEL IN DIESEL OR ETHANOL IN GASOLINE, The InfraCal 2 Biofuel Analyzer is a low-cost, single wavelength analyzer with filters preset for a particular measurement – either biodiesel in diesel or ethanol in gasoline. Biodiesel has a characteristic infrared absorption band at 5.73 μm (1745 cm-1). Ethanol’s infrared absorbance is at 9.6 μm (1045 cm-1). As the biodiesel or ethanol percentage increases, the infrared absorbance increases. An internal calibration table in the InfraCal 2 Biofuel Analyzer converts infrared absorbance to a digital readout in percent. A fuel sample is placed directly on the exposed ATR sample window and after 10 seconds the percent biodiesel or percent ethanol is displayed. The fuel is easily cleaned off the window using a solvent and a wipe and the analyzer is ready for the next sample.

The InfraCal 2 Biofuel Analyzers are ideal where a single, repetitive analysis is needed. InfraCal 2 ATR-B for measuring percent biodiesel has a measurement range of 0-100% biodiesel in diesel and an accuracy of +/- 0.2, the InfraCal 2 is based on proven IR technology developed by Wilks and used by regulatory agencies and fuel terminals worldwide. The compact, easy-to-use InfraCal 2 ATR-B measurement results are comparable to both ASTM D7371 and EN 14078.

Biodiesel in diesel 0.2-30% +/- 0.2 +/- 0.2
Biodiesel in diesel 30-100% +/- 1% of concentration

The InfraCal 2 ATR-E is the latest introduction to our easy to use analyzers for measuring ethanol in petrol. The InfraCal 2 ATR-E is a stand-alone fixed filter infrared instrument that gives results that are comparable to gas chromatographic methods and correlates with ASTM 4815.

Ethanol in gasoline 0-20% +/- 0.2
Ethanol in gasoline 70-98% +/- 1% of concentration
