Abstract
An interface for connecting an electrophoresis capillary to a mass spectrometer sprayer tube includes a first length of support tubing having an axial bore receiving and aligning the capillary and tube in end-abutting relationship at a junction. A solvent tube in a second length of support tubing intersects the first length of tubing in a T at the junction to supply makeup solvent to analyte flowing from the capillary to the sprayer tube. The tubing is secured in a T fitting which seals the tubing around the capillary, the sprayer tube, and the solvent tube.
