摘要: High throughput analytical systems and methods employing multiple liquid phase separation process regions coupled to a common mass spectrometer are provided. Disclosed systems and methods permits parallel separation and parallel storage of discrete eluate fractions, followed by sequential discharge and ionization of previously stored eluate portions to yield a composite ion stream containing the sequential series of eluate portions, followed by mass analysis of the ion stream. A common manifold may receive ions and utilize pressurized gas or ion gating to direct ions within the manifold toward the mass spectrometer inlet.

In certain embodiments, microfluidic devices are composed of sandwiched stencils, and self-adhesive tapes may be used for one or more layers. A microfluidic device may be removably attached to a vessel with a non-permanent adhesive or adhesive layer. Continuously wrapped microfluidic devices fashioned from a single layer, in addition to rewindable microfluidic devices constructed from multiple layers, are provided. A multi-plunger syringe permits a microfluidic device or other reservoir coupled to the vessel to be filled on the draw stroke of the syringe plunger.

摘要: Microfluidic flow control devices are provided. In one embodiment, a regulating device includes overlapping channel segments separated by a deformable membrane in fluid communication with one another. Pressure differentials between the channel segments deform the membrane towards the channel with the lower pressure, thereby restricting flow. The restricted flow increases pressure in the low pressure channel, reversing the deformation of the membrane and regulating the pressure between the channels
