Mass spectrometry of solution and apparatus

摘要

A mass spectrometric apparatus includes a device for supplying a sample solution to an outlet, the sample solution including a solvent and a solute, a first ionization device for receiving the sample solution from the outlet and electrospraying the received sample solution, thereby ionizing at least a portion of the received sample solution, a second ionization device for receiving at least a portion of the electrosprayed sample solution produced by the first ionization device and ionizing at least a portion of the received electrospayed sample solution, thereby producing ions, and a mass spectrometric device for receiving at least some of the ions produced by the second ionization device and analyzing masses of the received ions.
