Application Note: Evaluation of a ‘Soil Gas’ Sorbent Tube for Improving the Measurement of Volatile and Semi-Volatile Fuel Vapors in Contaminated Land
8 August 2014

This Application Note describes the development of a two-bed sorbent tube in conjunction with Markes’ Micro-Chamber/ Thermal Extractor for the sampling of petroleum, diesel and kerosene vapors collected from soil gas. Both lighter and heavier (polyaromatic, longer-chain) hydrocarbons were detected, and quantitative recovery is demonstrated for even the heaviest fuel components.
