Abstract
An apparatus for chemical separations includes a microfluidic substrate having an outlet aperture for outputting an eluent of a sample. An emitter assembly includes having a deformable end portion, an inlet near the deformable end portion to receive the sample eluent from the microfluidic substrate, and an electrically conductive outlet portion to emit a spray of the sample eluent. A force-applying unit applies a force to the emitter assembly that urges the deformable end portion into contact with the microfluidic substrate. The deformable end portion is more elastic than the microfluidic substrate so that the contact between the microfluidic substrate and the deformable end portion produces a substantially fluid-tight seal between the outlet aperture of the microfluidic substrate and the inlet of the emitter assembly.
