      In the world of environmental testing, many labs encounter extremely dirty samples. For example, EPA Method 1664B is the protocol for extracting oil and grease from wastewater samples. More often than not, these types of samples are really dirty, requiring loads of pre-filters, glass wool, and filter aid in order to get the entire liter of water through the disk. Well, there is!

      There’s nothing more satisfying than successfully extracting a really challenging sample. Solid phase extraction (SPE) is a powerful technique for extracting semi-volatile organic compounds and hexane-extractable materials (HEMs). When the chemistry is tailored to meet the requirements of the application, literally hundreds of compounds can be extracted with a single pass of solution through an SPE disk.
