WebHILIC is a particularly useful separation mode for polar organic compounds that are poorly retained by reversed phase. Retention of these polar compounds using reversed phase methods is often difficult because of … WebRinsing a column used for ion chromatography mainly targets removal of polyvalent ions and organic compounds. Using ions with high elution capacity or increasing the ion concentration is effective for rinsing off polyvalent ions. Conversely, an aqueous solution containing an organic solvent is effective for rinsing off organic compounds.
