<p>A cycling electrospray ionization device (5) includes a driving mechanism (51) and a nozzle (52). Thenozzle (52) is configured to sequentially form liquid droplets of an electrospray medium thereat, and is adapted to establish a traveling path with a receiving unit (6) of a mass spectrometer (2) such that when a potential difference is applied between the nozzle (52) and the receiving unit (6) to lade the liquid droplets with a plurality of electric charges for ionizing analytes to form ionized analytes, the charged droplets are forced to move toward the receiving unit (6) along the traveling path. The nozzle (52) defines a nozzle axis (L1), and is driven by the driving mechanism (51) to proceed with a cycling route (A) about a cycling axis (RC) such that the nozzle axis (L1) tracks along the cycling route (A), and such that immediately after leaving the nozzle (52), the liquid droplets cooperate to form a substantially columnar plume with a cross section substantially surrounded by the cycling route (A).</p> |
