Dionex (Sunnyvale, California) has agreed to purchase Caliper Life Sciences’ (Hopkinton, Massachusetts) AutoTrace solid-phase extraction (SPE) products, including the AutoTrace SPE workstation, which is designed to automate the extraction of large-volume aqueous samples before analysis. The system can be used for applications such as the EPA Methods 500 and 600 series for environmental testing of drinking water. Dionex intends to use the addition of the product line to focus on sample preparation in the water industry and to provide ion chromatography and high performance liquid chromatography methods for environmental analysis.
