Purge and Trap to detect Ethanol and 1 4 Dioxane
The United States Environmental Protection Agency (USEPA) Method 8260 uses Purge and Trap to detect Ethanol and 1 4 Dioxane. Both of these, ethanol and 1 4 Dioxane are water miscible and Selective Ion Monitoring (SIM) is required in order to detect these compounds at lower levels. The advent of SIM/Scan monitoring has made it easier to analyze for these compounds by traditional purge and trap sampling. However, due to the miscibility of the compounds and their propensity to stick to the sparge vessel of the purge and trap, purge and trap sampling needs to be optimized. This application will compare linearity, method detection limits, precision and accuracy and carryover of several purge and trap sampling parameters.
