Oil and grease (n-hexane extractable material) is a general indicator of the amount of hydrocarbons in a water supply. The Biotage Horizon 3100 automates the entire extraction process, fully compliant with US EPA Method 1664A/B, ISO 11349 and Standard Methods 5520B.
Dioxins are persistent organic pollutants (POPs) that are of concern around the world. They need to be efficiently extracted and then are usually measured with HRGC/HRMS using methods such as US EPA 1613 or ISO 18073:2004 for guidance. The SPE-DEX 4790 using solid phase extraction disks is a well-established technology that can be used for this application.
