## Abstract The sensitivity that can be obtained with the quadrupole ion trap for onโline CE analysis using a sheathless electrospray interface and goldโtipped columns is examined. Capillaries of different i.d. are compared in continuous infusion experiments and the effects of sheath solvents on th
Two previously unreported sources of systematic error in electrokinetic injection caused by induced (hydrodynamic) flow in sheathless capillary electrophoresis/electrospray have been characterized for an interface constructed from 5 pm i.d. capillary column(s) with a 2-5 pm i.d. electrospray tip(s).
