Solvent extraction using environmentally friendly siloxane solvents

摘要

A method (200) of performing a solvent extraction to quantify a contaminant of a sample by a hydrocarbon contaminant, the method (200) comprising the steps of: providing (210) a defined amount of the sample; providing (220) a defined amount of a siloxane Mixing (230) the defined amount of the sample and the defined amount of the siloxane solvent to extract the hydrocarbon contaminant from the sample to form a contaminant solution with the siloxane solvent; andstripping (240) the contaminant solution from the sample; exposing at least a portion of the separated contaminant solution to mass spectroscopic analysis, or gravimetric analysis, or magnetic resonance spectroscopic analysis.
