Samples that contain large amounts of sediment or particulates are difficult to extract using U.S. EPA Method 3535 (SPE, solid-phase extraction). While a standard 47-mm SPE disk is able to process a wide range of particulate-laden samples, longer processing times may result due to the size of the particulates.
The Fast Flow Sediment Disk Holder described in this article enables sample processing using a 100-mm prefilter with a 47-mm solid-phase extraction disk. In addition, high recoveries can be achieved using this disk holder.
