In this presentation from a recent 'Advances in Enviromental Analysis eSeminar' hosted by Separation Science in collaboration with PerkinElmer, Roberta Provost (Pace Analytical Services, USA) provides details of site studies in the analysis of soil gas to determine if targets are being missed.
Introduction
The current soil vapor intrusion (SVI) tube for analyzing toxic compounds in soil gas covers the analyte range from difluorodichloromethane through phenathrene. A tube has been developed to cover from 1,3-butadiene through the 16 EPA regulated polynuclear aromatic hydrocarbons (PAHs).
What is covered?
This research provides “side-by-side” experiments using the established SVI tube and the new XRO-440 tube to determine if analytes above the boiling point of phenanthrene are present in soil gas.
