Claim Text:
1. A microfluidic cartridge for chemical separations, comprising: a microfluidic substrate having a chromatography channel extending therethrough and a surface with an outlet aperture for outputting an eluent of a sample passing through the channel; an emitter assembly having an emitter including a lumen, an inlet end to receive the eluent into the lumen, and an outlet end with a spray tip to emit a spray of the eluent passing through the lumen; and a force-applying unit applying a force to the emitter that urges the inlet end of the emitter into flush contact with the surface of the microfluidic substrate to produce a substantially leakproof path for the eluent from the outlet aperture of the microfluidic substrate into the lumen.
