    摘要: The present method describes a method for recovery of aqueous samples or components thereof from polymer packaging materials, wherein the spilled aqueous sample has been absorbed by the packaging material to form a liquid swollen absorbent gel. The method comprises the steps of contacting the liquid swollen absorbent gel with a recover fluid, wherein the recovery fluid has a higher osmotic pressure then the aqueous sample, disrupting the gel and removing the recovery mixture for detection and analysis of analyte.
