Superheated Water as an Extraction Solvent in Sample Preparation
November 1st 2013Pressurized high temperature or superheated water is a green extraction solvent used in food, environmental, and traditional medicine studies for the extraction of non-polar and polar analytes including essential oils and spices, agrochemicals, pharmaceuticals, and petrochemicals.
Microwave Accelerated Extraction — SW-846 Method 3546 and Beyond
November 1st 2013Microwave accelerated extraction (MAE) was evaluated by the authors of this review in 1999 (1). Since this time, the United States Environmental Protection Agency (USEPA) has promoted the use of SW-846 Method 3546 using MAE for the extraction of organic compounds from solid matrices.
Green Chemistry Perspectives on Analytical Extractions
November 1st 2013The growing interest in green chemistry requires fresh perspectives on analytical extractions. Reduced solvent consumption, alternative safer solvents, and reasonable energy demands must be balanced with traditional analytical considerations such as extraction yield and selectively.
