Organic Acid Standards (4) (DE-413)

When water or 100% buffer is used as the eluent, the column life of ODS columns is usually shorten. Since the packing material of RSpak DE-413 is chemically stable, long column life and stable analysis results can be obtained even when Water or 100% buffer was used as the eluent.
