Analysis of Epichlorohydrin in Drinking Water by Purge and Trap GC/MS
Epichlorohydrin (ECH) is a versatile starting material in the production of drugs and polymers. It is also used as an insect fumigant and a solvent for organic synthesis reactions. ECH-based polymer pipes are widely employed in the production of drinking water. Due to its extreme reactivity and toxicity, many foreign nations have begun imposing limits on the amount of ECH allowable in drinking water. Drinking water analysis of volatile organic compounds (VOCs) is normally performed by purge and trap concentration using standard US EPA methods. Variations on these methods with modifications to the matrix and method parameters will be made to prepare the drinking water samples for analysis by GC/MS. Calibration data and method detection limits will also be presented.
