Abstract
An apparatus for chemical separations includes a microfluidic substrate having an outlet aperture for outputting an eluent of a sample, a spray unit having an inlet to receive the eluent and an outlet to emit a spray of the eluent, and a force-applying unit. The spray unit has a deformable portion defining the inlet and having an elastic modulus that is lower than an elastic modulus of the microfluidic substrate. The force-applying unit, such as a spring, is disposed to urge the deformable portion in contact with the substrate to form a substantially fluid-tight seal.
