Cetane index, density, aromatics, saturates, and hydrogen in jet fuel Fast and straightforward determination by near-infrared spectroscopy



A dedicated solution for quality control of jet fuel 02

Metrohm offers a turnkey solution for quality control of jet fuel by near­infrared spectroscopy (NIRS).

Based on a dedicated spectral database and a pre­calibration model, this solution enables manufacturers of jet fuel to reduce the cost of their daily routine analysis while improving the quality of their product.

Jet fuel is a product frequently used in civil and military NIRS on the other hand requires neither chemicals nor aviation.

Turnkey solution for jet fuel analysis 03

The Metrohm solution for jet fuel analysis comes with ready-to-use pre-calibration models for the determination of Cetane Index (CI or CETI), American Petroleum Institute gravity (API), aromatics, hydrogen and saturates content, density, flash and freeze point, viscosity or boiling points (T10, T20, T50). Thanks to these pre-calibrations, the Metrohm solution can be used as a starter model without any method development.

Such updates are easily performed in the Vision Air Manager network mode. When using Vision Air Network, all instruments within a global customer network can be synchronized at the push of button.

Customer specific calibrations can be easily developed for the determination of additional qua lity parameters of jet fuel, e.g. water content, pour point, benzene con tent and others.
