Method and system for analyzing hydrocarbon-containing samples

Abstract

The invention relates to a method and a system for analyzing one or more compounds in a hydrocarbon-containing sample. The method comprises steps of: a) injecting the sample and a first solvent into a chamber so that the one or more compounds in the sample form a precipitate in the chamber; b) passing the precipitate from the chamber to a filter device, wherein the precipitate is captured in the filter device; c) passing a second solvent through the filter device while bypassing the chamber, so as to dissolve the one or more compounds in the precipitate captured in the filter device; and d) detecting the one or more compounds downstream of the filter device. The system comprises a chamber, a sample feeding line, a first solvent feeding line, a filter device, a transfer line, a second solvent feeding line, and a detector.
