Regulatory agencies set threshold limits for volatile organic compounds (VOCs) based on threat, toxicity, and target matrix. Most water utilities, industry and dischargers have to monitor for VOCs in drinking water, surface water and wastewater using standard methods such as EPA 8260 & EPA 524.

In the first part of this presentation, Joel Kelly from Pace Analytical discusses the evolution of EPA method 8260. Technological advancements in gas chromatography/mass spectrometry (GC/MS) and Purge/Trap have improved chromatography, quickened run times and increased overall sample capacity, thus making sample runs easier and more efficient. These specific GC/MS improvements have allowed Pace Analytical to resolve difficult chromatography of the past with low limits of detection.

Bruce Quimby, from Agilent Technologies, spends the latter part of the presentation discussing data achieved using a 8860/5977B GC/MS instrument coupled with a Teledyne Tekmar Lumin purge and trap concentrator and an AQUATek liquid vial autosampler for the analysis of VOCs to the requirements of US EPA method 524.2. The applicability of the method was demonstrated using real-world drinking water samples, in which several VOCs were identified and quantified at concentrations varying over the range of 0.3 to 14.1 μg/L, in many cases much lower than current EPA 524.2 MDLs.

By viewing this presentation you will learn:

  • Advances that have been made in GC/MS and Purge/Trap technology, allowing to run method 8260 more efficiently.
  • How innovations in GC/MS technologies have improved sensitivity, chromatography and quickened run times.
  • Key parameters for success with the purge and trap method
  • An efficient way to build both the quantitation method and VOCs library using spectral deconvolution.

Who Should View:

  • Lab Managers
  • Environmental analytical chemist
  • Water quality professionals
  • Drinking water providers
  • Users of GC/MS
  • Environmental analysts
  • Environmental Laboratory Managers
