ABSTRACT

Sample preparation using solid phase extraction (SPE) has been in use for several decades. Over this time period the solid phases or sorbent materials used for extractions have been engineered into many different types and formats to solve specific or generic sample preparation problems in a wide variety of applications. This presentation will review the various silica and resin based sorbents used in environmental applications over time and use a selected SPE development case for semi-volatile organics to provide an example on how analytical challenges can be met utilizing multi-modal SPE. In addition a look towards where SPE media may be headed will be discussed.
