G-25 desalting purification cartridge is packed with gel filtration chromatography medium with dextran as the matrix. Separation is achieved according to the molecular size of the separated substances through the molecular sieve effect of the network structure in the dextran. During chromatography, molecules larger than the pore size of the gel are blocked out of the gel phase and travel along the gaps between the gel particles, with the fastest migration speed and, thus, are eluted first.
