A nanoinjector for microanalysis.

摘要: We describe a simple miniature injection device that can be used for introduction of nanoliter sample volumes in microfluidic systems. The hybrid microstructure consists two hydraulically connected parts, pulse micropump, and multilevel cross-flow injector. Sample is accomplished by creating transient pressure the line means solenoid-based micropump. aligned at right angles to main carrier flow line. channels are located different parallel planes. cross section defined self-sealing aperture an elastomer. During pulse, introduced through this directly into stream. Fast impulse-based causes rapid mixing injected with This permits single-line manifold micro (MFI) deformation/relaxation elastomer fast repeatable; as such, serial actuations ...
