Programmed-pressure chromatography

{
  "id": "MLC-T-CHM-013437",
  "term": "Programmed-pressure chromatography",
  "field": "Chemistry",
  "definition": "A chromatographic technique in which the pressure at the column inlet is deliberately changed according to a schedule during the run, which changes the flow of the mobile phase and so the retention times of the analytes. Raising the pressure speeds the elution of late-eluting compounds, and a slower program can resolve closely spaced peaks. It is a less common alternative to temperature programming and flow programming in gas or liquid chromatography.",
