  "term": "Column length",
  "field": "Chemistry",
  "definition": "The physical length of the tube or pipe containing the stationary phase in a chromatographic column. This parameter directly affects the separation efficiency and analysis time, with longer columns generally providing better resolution but requiring more time. Typical lengths for high-performance liquid chromatography columns range from 50 mm to 300 mm.",
