Solid phase extraction (SPE) is usually performed with disks or cartridges.  Horizon Technology provides two types of extractors to help in automating the process for better precision.  This allows each laboratory to choose the system that is most appropriate for their samples and workload. 

The Analysis of 1,4-Dioxane for EPA Method 522 and UCMR 3

by Horizon Technology
This Application Note will demonstrate the extraction of 1,4-Dioxane from an aqueous matrix using Option 1 of EPA Method 522 for 500 mL initial volume sample. It will make use of the SmartPrep Cartridge Extraction System to produce a valid Initial Demonstration of Precision (IDP) and Initial Demonstration of Accuracy (IDA).

How it Works: Capturing More Volatile EPA Method 8270 Compounds

by Horizon Technology
Using the Horizon Technology 8270 Carbon Cartridge Kit enables the capture of the more volatile 8270 compounds. The 8270 Carbon Cartridge Kit is designed for use with the Horizon Technology SPE-DEX 4790 Automated Extractor System, and the Oasis HLB (Hydrophilic-Lipophilic Balanced) solid phase extraction disk, developed by Horizon Technology and Waters Corporation.
