Scope

Scope: This document specifies the test method for analyzing the research octane number, motor octane number, ethanol content, other organic oxide compounds content, benzene content, aromatic hydrocarbon content, and olefin content of automotive ethanol gasoline (E10) using near-infrared spectroscopy. This document is applicable to the rapid analysis of quality indicators of automotive ethanol gasoline (E10). Main technical content: Using the overtone or combination of the stretching vibration of hydrogen groups in chemical bonds, the absorption spectra in the near-infrared region are obtained by transmission or reflection. Through modern chemometric methods such as principal component regression and partial least squares, a linear or non-linear relationship (correction model) between the near-infrared spectra of automotive ethanol gasoline (E10) products and their quality indicators is established, so as to achieve the rapid analysis of the research octane number, motor octane number, ethanol content, other organic oxide compounds content, benzene content, aromatic hydrocarbon content, and olefin content of the tested samples using spectral information.
