Peak parking

{
  "id": "MLC-T-CHM-008572",
  "term": "Peak parking",
  "field": "Chemistry",
  "definition": "A tactic in liquid chromatography coupled to mass spectrometry for gaining extra time to analyse a component that elutes in a narrow peak. When the front of the peak arrives, the flow of eluent is throttled to a minimal value and maintained there until the compound has passed. The stretched elution yields enough mass spectral scans for reliable statistics, and the slowing acts on the liquid flow, not on trapped ions.",
