Abstract:
Nano-electrospray ionization techniques include the introduction of a separation solvent containing a sample to a column-integrated needle having a column filled with a resin for liquid chromatography. The separated sample components are sprayed from the tip of the column-integrated needle toward a sample introduction orifice of a mass spectrometer. An organic solvent is simultaneously introduced to a solvent-supplying needle. The organic solvent is supplied from the tip of the solvent-supplying needle to the tip of the column-integrated needle.
