Its working principle mainly utilizes the function of molecular sieves to separate substances based on the different molecular sizes of the substances to be separated. After the sample enters the centrifugal desalination column, molecules larger than the maximum pore size of the matrix cannot enter the matrix gel. They move along the gaps between the matrix gel particles with the flowing solution at a relatively fast downward speed and are eluted from the column first. Molecules smaller than the pore size of the matrix will continuously enter the interior of the matrix gel pore size. Therefore, small-molecular-weight substances stay in the matrix for a longer time and move down more slowly, and are eluted after large-molecular-weight substances
