Application Note: Automated Solid Phase Extraction of PAH Compounds Utilizing the SPE-DEX 5000
6 November 2017
Polycyclic aromatic hydrocarbons (PAHs) can be found in a number of water types, such as drinking water, surface water, ground water and wastewater. There are serval types of extraction techniques that can be implemented to remove them from water for measurement including liquid-liquid extraction (LLE), continuous liquid-liquid extraction (CLLE) and solid phase extraction (SPE). break. SPE avoids the formation of emulsions, making extraction of a wide variety of sample matrices more predictable. It is more customizable through selection of a disk sorbent to target extraction to the range of analytes desired. Less solvent is used with SPE, minimizing the evaporation time and reducing the solvent potentially released into the atmosphere.
