hplc principle of working Secrets
The most typical RP stationary phases are based on a silica guidance, that's floor-modified by bonding RMe2SiCl, where R is a straight chain alkyl team including C18H37 or C8H17.By reducing the pH in the solvent in a very cation exchange column, As an example, additional hydrogen ions are offered to compete for positions on the anionic stationary p
