Brownian field-flow fractionation mode

{
  "id": "MLC-T-CHM-001516",
  "term": "Brownian field-flow fractionation mode",
  "field": "Chemistry",
  "definition": "A separation technique in field-flow fractionation where the applied field induces a force on the analytes, causing them to migrate towards one wall of the channel. The opposing force of Brownian motion creates a concentration gradient perpendicular to the flow. This mode is particularly effective for separating macromolecules and nanoparticles based on their diffusion coefficients.",
