Abstract A novel chemiluminescence (CL) flow-through sensor for the determination of analgin with flow-injection analysis (FIA) based on the auto-oxidation of analgin in the presence of Tween 80 sensitized by Rhodamine 6G immobilized on a cation-exchange column is described. This sensor responds linearly to the analgin concentration in the range of 0.4 ∼ 10 mg/L, with a detection limit (3σ) of 0.15 mg/L. A complete analysis, including sampling and washing, takes 1 min with a relative standard deviation of 〈 5%. The sensor is stable for over 200 determinations and has successfully been applied to the determination of analgin in pharmaceutical preparations.
