Low-pressure mercury lamp

{
  "id": "MLC-T-CHM-006794",
  "term": "Low-pressure mercury lamp",
  "field": "Chemistry",
  "definition": "A gas discharge lamp that emits ultraviolet radiation, primarily at 253.7 nm and 184.9 nm, from excited mercury atoms. It operates at a low vapor pressure of mercury, typically below 100 Pa, within a quartz envelope. These lamps are widely used for germicidal applications, photochemical reactions, and as calibration sources in spectroscopy.",
