ABSTRACT

Solid Phase Extraction (SPE) is a technology that has been around for several decades. The Green Chemistry benefits of reduced solvent usage, reduced solvent disposal cost and reduced solvent exposure to the analyst offered by SPE technology are more important today than ever before. However, many existing EPA methods still specify Liquid-Liquid Extraction (LLE) and the subsequent use of copious amounts of solvent, including dichloromethane, to perform the sample extraction. The author will review a variety of innovative developments that have been made in recent years to improve SPE technology so it can be more readily employed to help to make many existing EPA Methods “greener” in the future.
