Semi-micro solid-phase extraction of organic compounds from aqueous and biological samples

A technique is described for performing solid-phase extractions on a semi-micro scale. Thin membrane disks 4 mm in diameter containing lightly sulfonated polystyrene or Silicalite particles are placed in the hub of a syringe needle. Aqueous samples (1–6 ml) are passed through the membrane disks and...
