| titleOfInvention | Micro-fluidic three-dimensional focusing technology based nitrogen purging high-resolution mass spectrum electrospray ionization source and mass spectrum detection method |
| abstract | The invention belongs to the field of mass spectrum detection, and particularly relates to a micro-fluidic three-dimensional focusing technology based nitrogen purging high-resolution mass spectrum electrospray ionization source and a mass spectrum detection method. The ionization source comprises a chip and a film nozzle, wherein the chip is formed by sequentially bonding a first thick material layer engraved with a nitrogen purging channel 1, a film layer engraved with a sample liquid channel, a horizontal focusing liquid channel, a vertical focusing liquid channel, a nitrogen purging channel 2 and a nitrogen purging channel 3, a blank film layer and a second thick material layer engraved with a nitrogen purging channel 4 from the bottom up. According to the invention, an appropriate focusing liquid is selected to focus a sample liquid flow to be detected in the three-dimensional direction, and high-resolution mass spectrum analysis for ions of the sample to be detected is realized while restraining ion diffusion of the sample; and the sample liquid to be detected is purged by adopting four channels of nitrogen, thereby being capable of effectively improving the ionization efficiency of the sample to be detected, and improving the detection sensitivity of a mass spectrum. |
