Webinar: From Constraint to Opportunity: Optimizing GC Methods Post–Methylene Chloride Ban

19 Jun 2026

Free, On-Demand Access

In partnership with Shimadzu Corporation

The recent ban on methylene chloride has introduced significant challenges for EPA methods, particularly semivolatile analyses that rely on it as a primary extraction solvent. Mitigation strategies, such as reduced-volume extraction or alternative solvents, often introduce efficiency losses that must be compensated for elsewhere in the workflow. This webinar highlights how innovative GC column technology, paired with high-quality reference standards and optimized GC-MS/MS methods, can restore and exceed required sensitivity. Additionally, approaches for high-throughput, fast analysis will be discussed to help laboratories maintain performance and productivity under evolving regulatory constraints.

What You Will Learn

  • Learn about the impact of the methylene chloride ban on EPA 8270 semivolatile methods.
  • Learn about alternative extraction strategies and mitigations to achieve sensitivity.
  • Learn about GC column and GC-MS/MS optimizations to maintain or improve sensitivity and throughput.
  • Learn about how high-quality reference standards are critical for accurate and effective semivolatile analysis.

Who Should Attend

  • Environmental managers seeking strategies to mitigate the impact of the methylene chloride ban
  • Bench chemists aiming to optimize semivolatile methods for improved sensitivity and throughput
  • Procurement personnel focused on reducing cost per analysis while maintaining performance
  • GC users looking to enhance method performance and analytical efficiency
