Frontal Analysis or Displacement Frontal Analysis Concepts Continuously add sample to front of column Monitor components as they elute (exit from column) Provides a general measure of how compounds are retained on column Example - Charcoal flitration Frontal Analysis Process Materials (solute) move down a column of packed material by being displaced by a more highly retained solute

What’s the optimum mobile phase velocity?
When an acceptable level of separation is achieved, what
choice does the experimenter have regarding optimum mobile
phase velocity?
