Amides (3) (DE-413)

In order to separate hydrophilic compounds, water or 100% buffer solution is used as the eluent, however, such eluent usually shorten the column life of ODS columns. Since the packing material of RSpak DE-413 is chemically stable and has long column life. The stable analysis results can be obtained using DE-413 even when 100% aqueous solution is used as the eluent.
