Determination of 27 industrial dyes in juice and wine using ultra performance liquid chromatography with electrospray ionization tandem quadrupole mass spectrometry
超高效液相色谱-电喷雾串联四极杆质谱法检测果汁和葡萄酒中的27种工业染料

A method for the determination of 27 industrial dyes in juice and wine has been developed using ultra performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS).Acetonitrile was used as extraction solvent,and sodium chloride was added to salt out the analytes from the samples.Chromatographic separation was performed on a C18 column with the gradient elution and the mass spectrometric acquisition was carried out under the mode of multiple reaction monitoring (MRM).Twenty-four of the 27 dyes were...
