Determination of Poorly Volatile Resinous Substances in the Composition of Gasolines of Different Brands by Thermal Oxidation Spectroscopy–Oxythermography

A version of an oxythermograph based on the use of air oxygen as an oxidant is used for the determination of the total of poorly volatile compounds in gasolines. This allowed the elaboration of a rapid eco-friendly reagentless method for the determination of resinous substances in gasolines, requiring no chemical reagents and the subsequent utilization of the reaction products.
