The cell-stage eluent is chosen in such a way that it thoroughly stops interactions Using the stationary period's floor. Less than these ailments, the smaller sized the size from the molecule, the more it is ready to penetrate inside the pore Place plus the movement from the column can take longer. Alternatively, The larger the molecular size, the upper the probability the molecule will never totally penetrate the pores on the stationary section, and also journey all-around them, Therefore, might be eluted before.
An increase in counter ion (with respect into the useful groups in resins) concentration lessens the retention time, because it produces a strong Competitors Using the solute ions. A minimize in pH lessens the retention time in cation Trade even though a rise in pH lessens the retention time in anion Trade.
