The dyes were extracted from textiles composed of natural or chemical fibers by methanol under ultrasounication, and then eluted with gradient by acetonitrile and 5 mmol/L ammonium acetate from an RP-C18 column with two segments in effluents. The first effluents accommodated Acid Red 26, Direct Blue 6, Direct Black 38 and Direct Red 28 with negative ionization mode, while the second accommodated Basic Red 9, Basic Violet 14, Disperse Blue 1, Disperse Orange 11 and Disperse Yellow 3 with positive ionization mode. Thus the investigated compounds could be identified simultaneously with single-run analysis no matter which type of the fibre the sample was and no matter which category of the dye the analyte was.
