Automated Solid-Phase Extraction of Oraganochlorine Pesticides from Drinking Water

14 Aug 2014

In this poster a new method to automate the capture and elution of organochlorine pesticides from drinking water is described. Twenty chlorinated pesticides were extracted from drinking water using a Thermo Scientific™ Dionex™AutoTrace™ 280 Solid-Phase Extraction instrument and the Thermo Scientific™ Dionex™ SolEx™ C 18 cartridges with good recoveries. The traditional LLE method also showed good recoveries, but was time consuming and labor intensive.

Thermo Fisher Scientific

The Thermo Scientific™ Dionex™ AutoTrace™ 280 Solid-Phase Extraction (SPE) instrument is a powerful, high-throughput workstation dedicated specifically for automating SPE. The Dionex AutoTrace 280 instrument automates the cartridge or disk conditioning, sample loading, rinsing, and eluting steps for large volume aqueous solution extractions (20 mL to 20 L).The unit can process up to six samples in parallel, automatically conditioning, washing, and eluting SPE cartridges or disks with a choice of up to five reagents. The unit also segregates aqueous and solvent waste using separate waste lines for efficient, cost effective waste handling.AutoTrace 280 Solid-Phase Extraction Instrument Features: Use SPE technology for liquid-liquid extraction Automated sample loading of liquids onto SPE cartridges Automated eluting of SPE cartridges with organic solvent Closed systems with a fan to vent solvent vapors Positive pressure loading and elution of samples and solvents Benefits: Reduced solvent usage and elimination of glassware Does not require technician involvement to maintain a reservoir of liquid in the SPE cartridge Does not require technician involvement to control the flow of organics solvent through the SPE cartridge No hood required Provides constant flow of liquids through SPE cartridges
