  • Sample preparation method for analysis of acrylamide
    Patent number: 9995663
    Abstract: The present invention relates to a method for extracting acrylamide from a matrix comprising matrix components and acrylamide, comprising the steps: bringing said matrix in contact with water to obtain an aqueous extract, and, optionally, adding a base to the aqueous extract; loading a portion of the aqueous extract obtained in the previous step onto an inert support; allowing the inert support to absorb the aqueous extract; extracting acrylamide from the aqueous extract by passing a water immiscible organic solvent through the inert support; thereby obtaining an organic extract. It further relates to a method for analyzing acrylamide content in a matrix comprising matrix components and acrylamide.
    Type: Grant
