Abstract
A liquid-chromatography module includes a microfluidic cartridge housing a microfluidic substrate with a channel for transporting fluid. The microfluidic substrate has fluidic apertures through which fluid is supplied to the channel. One side of the cartridge has nozzle openings, each aligning with a fluidic aperture in the microfluidic substrate and receiving a fluidic nozzle. A clamping assembly has a plunger that is movable into a clamped position and an end housing that defines a chamber. One wall of the end housing has a fluidic block with fluidic nozzles extending into the chamber. A second wall has a slot through which the cartridge enters the chamber. When moved into the clamped position while the cartridge is in the chamber, the plunger urges the cartridge against the fluidic block such that each fluidic nozzle enters one nozzle opening and establishes fluidic communication with one fluidic aperture in the microfluidic substrate.
