DryDisk® Disks & Barrels

The City of Fort Worth, Water Department conducted an evaluation of the Atlantic™ solid phase extraction (SPE) C18 disks using EPA Method 608. This application note describes the procedure to determine low ppb levels of organochlorine pesticides and PCBs in wastewater. This procedure used methylene chloride as the primary extraction solvent, followed by a hexane solvent exchange. Extracts were then analyzed by GC/ECD using a pressure pulse injection technique.

EPA Method 608 describes the procedure to determine low parts per billion levels of organochlorine pesticides, polychlorinated biphenyls, toxaphene and chlordane in wastewater. The laboratory that collected the data presented in this application note uses EPA method 608 ATP3M0222 as the approved SPE technique for waste water extraction. The disks compared in this study are : “Certified for Automation” Atlantic™ C18 (47 mm) and 3M Empore™ High Performance Extraction Disk C18 (47 mm). Comparisons were made using side-by-side extraction and identical calibration parameters.

Method 1657 describes the procedure to determine low ppb levels of organophosphorus pesticides in municipal and industrial wastewater. The City of Fort Worth Water Department implemented Automated SPE for the analysis of organophosphorous pesticides by EPA Method 1657, using the Atlantic™ C18 solid phase extraction disk. The Biotage® Horizon 4790 Automated Extraction System with Envision® Platform controller, and the DryVap® Automated Drying and Concentration System were used in this application note.

EPA Method 506 is used to determine Phthalate and Adipate Esters in drinking water. The analytes are extracted from water using a Horizon Technology 47 mm Atlantic C18 disk. The disk is extracted with Acetonitrile and Methylene Chloride. The extract is then dried and concentrated to a final volume of 1.0 mL using the Horizon Technology DryVap® with DryDisk® technology. Final analysis is by GC/PID.

This study shows that the Biotage® 4790 Automated Extractor system, along with the Atlantic™ DVB disk, the DryDisk® separation membrane, and the DryVap® Concentrator System can be successfully used to analyze for Nonyl Phenol and Bisphenyl A in water samples. This sample preparation process is fully automated, requiring minimal human intervention, and allowing for reductions in sample processing costs.

The DryDisk membrane drying system provides advantages for removing water from nonpolar solvents, important in protecting the chromatograph in the analysis step, especially critical in protecting GC and GC/MS.

Removing water with a membrane rather than the older technique of passing the solvent through a column of sodium sulfate (Na2SO4) brings several advantages. The most important analytically is that the membrane will not adsorb analytes or contaminate the extract with matrix or other potential interferences.
