Application Note: Improve Recoveries of Chlorinated Pesticides with CarboPrep® SPE Cleanup
20 June 2013

In this application note it is demonstrated that adding a CarboPrep® SPE cleanup step for the recovery of chlorinated pesticides is an effective way to minimize interferences and improve method accuracy. Many chlorinated pesticides have been banned for use because of their short- and long-term toxicity, carcinogenicity, and environmental persistence. An expanded list of these chemicals, some of which are still actively applied in the field, has been included in the updated US Environmental Protection Agency (EPA) Method 8081B.One of the primary challenges chemists face with 8081B analysis is chromatographic interference from matrix compounds.
