Definition of Analytical Extraction

Extraction is the process of moving one or more compounds of interest (analytes) from their original location (usually referred to as the sample or matrix) to a physically separate location where further processing and analysis occur. The sample may be a solid, liquid or gas. The separate location is usually a fluid (an extracting solvent), but extractions into the gas phase and on to solid sorbents are also common. Finally, the word analytical implies that this process involves small amounts of analyte (as opposed to preparative extraction). Most analytical methods aim at complete extraction although situations frequently exist where good analytical results are possible with only partial extraction.
