Investigation of heavy fraction in gasoline by GC-MS

Abstract

Investigation of gum fraction in gasoline sample using GC-MS. In accordance with the theory of formation of resinous fraction during storage, the identification of compounds is based on comparative analysis with reference to NIST library. The composition of heavy fraction and Resinous content was revealed to some extent, a general aspect of the gum arrangement was presented and an evaluation method was developed to serve this purpose.
