Analysis of wastewater samples using disk SPE following US EPA method 608.3

The Horizon 5000 automated extraction system is a programmable, multipurpose SPE system, capable of processing aqueous samples directly from their original containers. Once the process is initiated, each Horizon 5000 module delivers all the necessary solvents to precondition the sorbent material within the SPE disk, passes the water sample through the disk and, after a preset air-dry time, extracts the sorbed analytes from the disk into a collection vessel using the required amounts of solvents.

This work demonstrates the use of SPE disks on wastewater samples using automation to provide control and consistency in all the steps in the extraction process, including conditioning the disk, loading the water sample, rinsing the sample bottle and eluting the sample in solvent.
