There is a worldwide need to measure dioxin/furans in real or near real time in flyash matrices from incinerators to meet the Environmental Standards. This report describes the performance of a fast GC/SAW measurement system, which was successfully used to analyze flyash samples supplied by A Japanese Company. Although a GC by itself cannot positively identify dioxins/furans, it can provide a near real time field measurement and is a cost effective screening tool which can minimize expensive laboratory GC/MS testing.
