Air Monitoring: New Advances in Sampling and Detection

<table>High-concentration vapours from a light diesel fraction collected into a canister and analysed using TD–GC/MS (CIA-<i>Advantage</i> system, Markes International Ltd); selected peaks are indicated and their approximate concentrations given. Black trace: 2 mL sample taken using a gas loop. Blue trace: 100 mL sample taken using an MFC. Inset: zoomed-in plot, demonstrating the greater sensitivity that results from using MFC sampling (method conditions are shown in Table <a href="430616.tab4.html">4</a>).</table>
