Embodiment 1
[0039] Such as figure 1 , As shown in 2, 3, the microfluidic free paper chromatography array spray mass spectrometry device includes a microfluidic control device 14, a microfluidic free flow paper chromatographic separation device that is a microfluidic carrier plate 4, a microfluidic cover plate 6, Paper stationary phase 10, and array spray component 11, mass spectrometry component. In this embodiment, the paper stationary phase 10 is placed in the separation cavity 2 formed by the microfluidic carrier plate 4 and the microfluidic cover plate 6 to ensure that the device is sealed. The buffer or mobile phase enters the separation chamber 2 through the first pipe 1 through the microfluidic channel 7, and the sample enters the separation cavity 2 through the second pipe 3 through the sample channel 8; in this embodiment, microfluidic control is used The device 14 controls the sample loading and the flow control of the buffer or mobile phase. The microfluidic control device 14 c...
