All our HPLC columns are shipped to you in the shipping and delivery solvent. For reversed period columns this commonly is made of a particular composition of natural (acetonitrile or methanol) and drinking water.Solute ions billed similar to the ions over the column are repulsed and elute devoid of retention, even though solute ions charged opposi
