Indirect UV-detection in single-column ion chromatography


Several aromatic acids and their salts were studied as eluents for indirect UV detection. Relation between detection sensitivity and factor of molar absorptivity of the eluent, its concentration and elution strength was showed. Separation of seven inorganic anions mixture was realized on sorbent Nucleosil SA modified with 3,6-ionene by present eluents. The low limit of anion BF4 detection was reached. It was better as compared with double-column ion chromatography with conductometric detection.
