1. disabling the rapid detection method of Sudan red dyes in a kind of lipstick, characterized by the following steps:

  • (1) make triangle carrier;

    the triangle carrier is to be cut out using Whatman Grade 31ET Chr type chromatographic paperAt the triangle scraps of paper, uniformly smear lipstick sample to be detected on the triangle carrier;

    The triangle carrier be etc.Lumbar triangle shape, a length of 0.5cm in bottom edge, a height of 0.75cm, apex angle are 30 °

    (2) make detection device;

    the detection device includes metal crocodile clip, metal frame, high voltage power supply and ion trap mass spectrometer,The metal crocodile clip is fixed in the metal frame, is fixed on metal crocodile clip in the middle part of the bottom edge of the triangle carrier,The rear end of the metal crocodile clip is connected with the high voltage power supply, and the triangle carrier is placed on the ion trap mass spectrometerInjection port front end;

    (3) it detects;

    the mixed solution of methylene chloride, ethyl alcohol and formic acid being added dropwise on the triangle carrier, using high voltage power supply4.0 kilovoltages are applied to metal crocodile clip, the mixed solution carries out the Sudan red dyes to be measured in the lipstick sampleIt extracts, and then is migrated on the triangle carrier to its tip direction, finally form spraying, the ion trap matter at tipSpectrometer is detected using positive ion mode;

    The disabling Sudan red dyes to be measured are Sudan red 1, Sudan II, Sudan red III and Sudan IV;

    The Sudan to be measuredThe test condition of red dye is as shown in table 1;

    1 test condition of table
