  "term": "Flow field-flow fractionation",
  "field": "Chemistry",
  "definition": "A separation technique within the field-flow fractionation family that uses a parabolic flow profile across a thin channel to separate particles or macromolecules based on their diffusion coefficients. A perpendicular flow, or cross-flow, is applied to drive components towards one wall. This method is effective for separating complex mixtures of colloids and polymers.",
