GC/MS Analysis of Aromatics in Gasoline using ASTM D5769: Set-up, Optimization, and Automated Reporting

The unavailability of fluorescence dye has impacted the widely used D1319 method for determining total aromatics in reformulated gasoline. To remain in compliance with EPA regulations, many labs are considering the more complex D5769 GC/MS method for total aromatics analysis.

Successful performance of a GC/MS system depends on good chromatography, an inert flow path, and low background signal, where the quality of the carrier gas, whether achieved with filters or high-grade gas supply, and leak free connections play important roles in flow path and low backgrounds. Easy-to-use products for monitoring gas filter lifetime and installing columns help in the set-up and routine operation to increase the uptime of the GC/MS system.

This presentation will offer best practices for setting up, optimizing, and running this method on a new, cost-effective GC/MS system. Data analysis approaches will also be discussed with emphasis on a new system for automated reporting of results.

By attending this webinar you will...

• Understand the different ASTM configurations and operations of D5769
• Learn techniques to optimize the Agilent 8860/5977 GC/MS system for running D5769
• Understand how the 8860/5877 GC/MS system performs for different D5769 configurations
