  "id": "MLC-T-CHM-008577",
  "term": "Peak width at half height",
  "field": "Chemistry",
  "definition": "The horizontal distance across a chromatographic or spectral peak measured at half of its maximum height. This parameter is inversely related to the efficiency of a separation or the sharpness of a spectral feature. It is commonly used in chromatography to calculate the number of theoretical plates and assess column performance.",
