ABSTRACT:
Disclosed herein is an electrospray device for mass spectrometry that includes a fluid inlet, an outlet orifice, and a passage for fluid communication between the fluid inlet and outlet orifice. This passage is formed from a capillary (i.e., a first capillary). This first capillary (3) partially houses a second capillary (7) such that the outlet orifice is narrowed. A portion (17) of the second capillary extends beyond the first capillary. This extension permits a practitioner to clip away obstructed portions of the second capillary.
