The invention relates to a rotary electric spraying free device, which comprises a rotating mechanism and at least one spray nozzle, wherein the rotating mechanism can rotate around a center axis, the spray nozzles are arranged on the rotating mechanism in a way of being separated from the center axis, the spray nozzles can rotate around a rotating center for forming a sealed moving trace so that the spray nozzles can simultaneously spray electric spraying liquid drips when rotating along the moving trace. The invention also provides a mass spectrometer and a mass spectrometric analysis method. The spray nozzles spray the electric spraying liquid drips in a way of rotating along the moving trace so that each electrically sprayed charged particle (liquid drip) is uniformly distributed in the spray space, the mutually repelled space charge effect of the charged particles is overcome, the number and the proportion of most mini charged particle streams formed by electric spraying entering a mass analyzer inlet in the mass spectrometer are increased, the ion signal stability and the intensity can be improved, and the sensitivity of the spectrometric analysis can also be effectively improved.
Description
technical field [0001] The present invention relates to an electrospray ionization (ESI) device, in particular to a rotating electrospray ionization (RESI) device for electrospraying aerosol droplets to be analyzed in a rotating manner. The present invention also relates to a mass spectrometer including the rotary electrospray ionization device, and a mass spectrometry analysis method. Background technique [0002] With the help of mass spectrometry technology, people can know the molecular weight of the analyte in a sample, and then cooperate with further comparison to confirm the true identity of the analyte. Therefore, since the early 20th century, it has been used to implement the mass spectrometry technology The mass spectrometer has become a widely used identification tool in various fields because of its advantages of easy operation and quick detection results. [0003] A general mass spectrometer mainly includes three major components: a dissociation device, a mass ...
