The Use of Near-Infrared Spectroscopy for Quantitative Analysis of Gasoline/Methanol Mixtures
MetadataShow full item record
The purpose of the study was to investigate the feasibility of utilizing near-infrared(NIR) spectroscopy as a tool for the analysis of gasoline and methanol mixtures. In this effort, the following criteria were established: the ability to accurately quantify concentrations of methanol for all gasolines, a means of compensating for inherent temperature effects, stability of the readings despite emulsion of gasoline and methanol, and the compatibility of such technology with existing automobile design. In addition, together with the above mentioned goals, another avenue for research became the possible usage of NIR to pinpoint aromatic content of gasoline for a number of industrial applications. By way of limitations, this research focuses on the chemistry of NIR spectroscopy and its usage, rather than the ultimate goal of implementation. As a result of this research, a prototype apparatus has been devised and is currently being tested. The details of this working model, however, entail engineering concepts which deviate from the scope of this research. In addition, no mention of the developed apparatus will follow, due to pending patent procedures.
