A method for extracting at least one target compound from a sample includes injecting an overloaded amount of the sample into a chromatographic conduit ( 110 ), and flowing a solvent having a time-varying composition through the conduit ( 110 ). An apparatus for extracting at least one target compound from a sample includes a chromatography module, a mass-spectrometry module in fluid communication with the chromatography module to receive a portion of an eluent from the chromatography module, and a control unit in communication with the chromatography module and the mass-spectrometry module.
