Electrochemical quartz crystal microbalance

  "id": "MLC-T-CHM-003662",
  "term": "Electrochemical quartz crystal microbalance",
  "field": "Chemistry",
  "definition": "An analytical instrument that measures minute mass changes at an electrode surface by monitoring the resonant frequency of a quartz crystal oscillator. When a substance is deposited or adsorbed onto the crystal's surface, its mass increases, causing a measurable decrease in the resonant frequency. This technique is often used to study electrodeposition, corrosion, and adsorption phenomena.",
