Sulfite ion chromatography standard
Web15 Aug 2024 · Sulfite ion is a weak base, but does undergo some hydrolysis to produce basic solutions. In acidic solution, the equilibria are shifted to form sulfurous acid, resulting in the evolution of SO2 gas. Sulfur dioxide is a colorless gas with a characteristic choking odor. SO2 − 3 (aq) + H 2O(l) − ⇀ ↽ − HSO − 3 (aq) + OH − (aq) wiht Kb = 1.8 × 10 − 7 Web12 Apr 2024 · Ion chromatography (IC) is used for analysis of inorganic and organic ions. It is categorized as suppressor IC and non-suppressor IC. Non-suppressor IC is composed of a conventional HPLC system combined with a conductivity detector, while suppressor IC requires an extra suppressor. Product Information
