Multiple solid-phase microextraction in a non equilibrium situation. Application in quantitative analysis of chlorophenols and chloroanisoles related to cork taint in wine

Multiple HS-solid-phase microextraction (MHS-SPME) is a modification of SPME developed for quantitative analysis that avoids possible matrix effects based on an exhaustive analyte extraction from the sample. In this paper, the theory of this process associated with a non-equilibrium situation has be...
