Water accommodated fractions (WAFs) of petroleum are created under various environmental conditions. The resulting water soluble species are of environmental interest since they may be toxic to aquatic life. Traditional liquid/liquid separations use large volumes of hazardous solvents.  Development of new solid phase (SP) chromatography methods for the separation of acid, base and neutral species in WAFs reduce the volume of potentially harmful solvents used. Species class identification was then accomplished with gas chromatography - mass spectrometry (GC-MS) and high performance liquid chromatography (HPLC).
