T/CPCIF 0184-2022 Car gasoline rapid analysis method: Near-infrared spectroscopy
Basic Information
Scope
Scope: This document specifies the test method for analyzing the research octane number, motor octane number, benzene content, aromatic hydrocarbon content, olefin content, oxygen content, and methanol content of automotive gasoline using near-infrared spectroscopy. This document is applicable to the rapid analysis of automotive gasoline quality indicators; Main technical content: By using the overtone or combination of the stretching vibration of hydrogen-containing groups, 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 gasoline products and their quality indicators is established, thereby enabling the rapid analysis of the research octane number, motor octane number, benzene content, aromatic hydrocarbon content, olefin content, oxygen content, and methanol content of the tested samples using spectral information.
