Disclosed are a device and method for measuring fluorescence signal in multi-illumination mode and use of the method. An excitation light is modulated on an illumination excitation light path, to generates excitation illumination patterns at different phases on a sample after passing through an objective lens; a high-speed switching device is arranged on a fluorescence collection light path to switch the position of a fluorescence image of the sample on a target plane of a photoelectric sensor, and a plurality of sub-images can be simultaneously obtained after one exposure through synchronous operation of multi-illumination excitation light paths and fluorescence imaging light paths, which correspond to fluorescence signals in a plurality of illumination modes.

The present disclosure relates to a method for detecting the contents of whey protein and casein, and/or the ratio thereof in milk powder by liquid chromatography-mass spectrometry. According to the method of the present disclosure, the characteristic peptide segments of whey protein and casein are selected and used for correction, and thus the accuracy and stability of detection of peptide segments by mass spectrometry using external standards are improved; in addition, the method of the present disclosure has the following advantages: easy to pretreat samples, low cost, a wide range of applicability, enable to perform quantitative detection of whey protein at one time, not affected by protein denaturation in the production process, no need to synthesize isotope internal standard, and avoiding influence of ionization efficiency and matrix in mass spectrometry detection by means of their own multiple characteristic peptide segment ratios.
