Objective To determine 15 kinds of industrial dyes simultaneously in condiments with high performance liquid chromatography(HPLC).Methods Samples were separated on a CAPCELL PAK C18 MG(250 mm×4.6 mm,5 μm)chromatographic column and gradient eluted with nitrofuran-acetonitrile-20 mmol/Lammonium acetate and detected at 450,530 and 600 nm.Results The calibration curve showed good linearity in the rang of 2~50 μg /ml,and the correlation coefficients were better than 0.99.The limits of detection were ...
