Embodiment 1
[0032] figure 2 The migration spectrum of pure melamine detected by ion mobility spectrometry is given, as can be seen from the figure, melamine is well detected, the reagent ion peak is at 4.34ms, and the characteristic peak of melamine is at 8.48ms.
Embodiment 2
[0034] image 3 Shown is the mobility spectrum of a milk sample detected by ion mobility spectrometry. From two graphs ( figure 2 and 3) comparison, it can be seen that this method can sensitively detect melamine in milk samples.
Embodiment 3
[0036] Figure 4 Shown is the mobility spectrum of the milk powder sample detected by ion mobility spectrometry. From two graphs ( figure 2 and 4 ) comparison, it can be seen that this method can also sensitively detect melamine in milk samples.
