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 () partially houses a second capillary () such that the outlet orifice is narrowed. A portion () of the second capillary extends beyond the first capillary. This extension permits a practitioner to clip away obstructed portions of the second capillary.
