High-Performance Liquid Chromatographic Determination Of N-Nitrosoamines by Pre-Column Fluorescence Derivatization with 9-Phenanthrene Chloride

Department of Chemistry Qufu Normal University Qufu Shandong 273165

Received Date: 22 April 1995

A sensitive high-performance chromatographic method for the detection of N-nitrosoamines with pre-column fluorescence derivatization has been developed.Eight representative N-nitrosoamines,which were separated on a reversed-phase C₁₈column with methanol-water-triethylamine as eluent,were used as model compounds to optimize the derivatization and the chromatographic conditions.The relative standard deviations(n=7) at an analytical concentration of 4×10^-6 mol/L are less than 5%.The detection limits (signal-to-noise ratio=3) for the N-nitrosoamines compounds are in the range of 0.02~0.14 nmol per injection volume(10 μl).
