Determination of Method Detection Limits for Chlorinated Acids in Ground and Drinking Water utilizing an Automated SPE-DEX® System

This application note presents EPA Method 515.2, which is applicable to the determination of chlorinated acids in ground water and finished drinking water. Analytes are extracted from the water using a DVB-Hydrophobic disk and the Horizon Technology SPE-DEX^® 4770 Automated Extraction System and final analysis is done by GC/ECD. This work on the determination of method detection limits (MDLs) for chlorinated acids demonstrates the capability of the Horizon Technology SPE-DEX^® 4770 for the automated SPE of organic compounds.
