There is an increasing need to measure both volatile and semi-volatile components in air since impact to human health are concerns. Currently, the analysis of volatile and semi-volatile components requires two methods EPA TO-15 or TO-17 for VOCs and EPA TO-13A for SVOCs. The purpose of this new, innovative, and novel research first published in 2014 is to analyze all of these components using one analytical method following EPA TO-17.

TO-17 captures target analytes in air, via active sampling, with specified adsorbents. To enable the analysis of VOCs and SVOCs in air, a new tube design was developed to quantitatively provide results from 1,3-butadiene up to benzo(g,h,i) perylene; a component boiling point range from nC4 to cC44. All 16 regulated PAH targets and volatiles in one air sample!

The advantages of the one analysis solution include reduced sampling costs, enhanced laboratory productivity, profitability, and safety. Unlike TO-13, TO-17 does not require solvent extraction making TO-17 a greener approach.

By viewing this presentation you will learn about...

• data that will demonstrate both field and analytical soundness of this combined method
• site studies where side-by-side sampling and analysis were performed between the TO-15/TO-13 methods and the TO-17 method
