    Reference Separation of solvent  Processing time can be reduced by separating solvent with a high oil concentration from solvent a low oil concentration before reclamation. Keep solvent, which has been used for calibration and measurement in containers separate from unused solvent, and further separate by use and/or oil concentration. For example, it is recommended that zero calibration liquid, span calibration liquid, low concentration sample liquid, and high concentration sample liquid are reclaimed separately.
