Detailed Hydrocarbon Analysis by GC-VUV Using ASTM D8369

User Benefits

- GC VUV enables detailed compositional analysis of gasoline in accordance with ASTM D8369. - VUV Analyze facilitates peak deconvolution and quantitative calculations, simplifying data processing.

Introduction

The composition of fuels such as gasoline, diesel, and jet fuel critically influences physical properties including combustibility; therefore, detailed compositional information is of high importance. Gasoline typically comprises a complex mixture of over one hundred hydrocarbons, making qualitative identification of individual constituents highly time consuming. ASTM D8369 defines procedures for the qualitative and quantitative determination of hydrocarbons and oxygenates (e.g., ethanol additives) in gasoline using a vacuum ultraviolet (VUV) detector. In this application news, we present a compositional analysis of gasoline conducted on a Nexis GC 2030 system in compliance with ASTM D8369. The VUV analysis software VUV Analyze was employed to perform peak deconvolution and quantitative calculations efficiently.
