Thermal sampling head and system for concrete walls

PDF Version Also Available for Download.

Description

We have determined that the thermal sampling approach gives more accurate results of analyte levels on concrete surfaces when compared to the standard wipe test methods. The use of a quick-look detector eliminates the need to analyze ``clean`` environmental samples. The sorption tubes have been shown to provide a reliable quantitative means for transfer of analyte to an automated thermal desorption interface to a GC. We will be extending our work to include sampling of steel surfaces in Phase II of this program. Models of the extraction process for porous surfaces such as concrete will be developed in the next ... continued below
