  "id": "MLC-T-CHM-010649",
  "term": "Sedimentation coefficient",
  "field": "Chemistry",
  "definition": "The ratio of the constant sedimentation velocity of a particle to the applied acceleration field causing the sedimentation. It quantifies how quickly a particle settles in a fluid under the influence of an external force, such as gravity or centrifugation. The sedimentation coefficient is typically expressed in Svedberg units (S).",
