Abstract

the separation of elements is achieved by ultra performance liquid chromatography system for Aflatoxins, the use of a closed-loop feedback control system is to produce a stable continuous wave light source, fixed wavelength of 360nm illumination light source onto the separation of elements, resulting in the emission wavelength was 440nm receiving photomultiplier tube, and then it gets high-frequency pulses. By single photon counting system pulse will be integrated for a fixed time , aflatoxin can be obtained G1, B1, G2, B2 content elements through the peak area calculation. Without derivatives quantitative determination of aflatoxin can be carried out quickly and efficiently. This design can effectively address the impact of the stability of the light source on the test results. It is useful for analysis LED spectral characteristics.
