Question/Answer

Is the Polypropylene, disposable funnel approved by the EPA as an alternative to glass?

The EPA only approves methods, not equipment and supplies. EPA 1664 is the method that is approved for the analysis of hexane extractable material. The method is written for liquid-liquid extraction and carries guidance for using solid phase extraction as a method modification. There is no mention of any requirement for the material used to construct the solid phase extraction equipment.
