ASE is commonly used to extract polycyclic aromatic compounds (PAC) from solid matrices. The development of ASE for PAHs can be traced to the 1990s. Recently, a one-step ASE method that negated the need for adsorption chromatography was reported to extract PAHs from marine sediments. Inspired by the previous work, the Centre for Oil and Gas Research and Development (COGRAD) decided to further investigate the one-step ASE method for PAHs on two standard reference materials. The goal was to verify the suitability of the one-step method and its applicability to improve laboratory efficiency.
