Optimization of 1,4-Dioxane Analysis By Purge And Trap – GC/MS

Testing for 1,4-Dioxane at low levels can be problematic due to its affinity for water, decreasing its volatility and purge efficiency by traditional purge and trap methods. Most systems struggle to maintain system cleanliness due to high a degree of carry over. This application note describes an optimized method, which dramatically reduces carryover, yet maintains a large dynamic range (1ppb-2000ppb).
