Abstract Use of early solvent vapor exits for concurrent eluent evaporation with the loop‐type interface has two purposes: protection of the GC detectors from large amounts of solvent vapors and more efficient discharge of the vapors to accelerate eluent evaporation and help avoiding broad solvent peaks. Use of a retaining pre‐column after the uncoated pre‐column can rule out losses of solute materials that form sharp peaks.
