The purity of a solute collected between two times t1 and t2 during chromatographic separation can be calculated as
amount of solute eluted - amount of impurity eluted
amount of solute eluted / amount of impurity eluted
amount of solvent eluted + amount of impurity eluted
amount of solvent eluted / amount of impurity eluted

Chromatography is based on the
different rate of movement of the solute in the column
separation of one solute from other constituents by being captured on the adsorbent
different rate of movement of the solvent in the column
any of the above

The correlation often employed to correlate adsorption data for protein is (where Ymax is the maximum amount of solute adsorbed per mass of adsorbent, X is the mass fraction of solute in the diluent phase in solute-free basis, KL is a constant and Y is the equilibrium value of the mass of solute adsorbed per mass of adsorbent)
Y = YmaxX/(KL+X)
Y = Ymax/(KL+X)
Y = YmaxX/KL
Y = Ymax- X/ (KL+X)
