Elute off the column
WebSolutes between these two ranges of molecular mass will elute between the excluded and included volumes . Figure 3.4.2.2: Excluded vs. included volume . As a general rule of thumb, the excluded volume (Vo) is approximately equal to one third of the column volume, the included volume is approximately equal to two thirds of the column volume WebJul 24, 2024 · The selected concentration is used to find out the optimum volume of the eluent to elute the H + ions completely as a measure of the column efficiency. The results showed that only 120 mL of the eluent was required to elute the H + ions completely from the cation-exchange column, which indicates good column efficiency ( Figure 4 ).
