Isobaric separation

  "id": "MLC-T-CHM-006169",
  "term": "Isobaric separation",
  "field": "Chemistry",
  "definition": "A chromatographic separation carried out with constant inlet and outlet pressures, so that the pressure drop across the column stays fixed during the run. It is the constant-pressure counterpart of constant-flow operation. In gas chromatography with a temperature program, the carrier gas flow rate then falls as the column heats up, because the viscosity of the gas rises.",
