    摘要： Microfluidic devices provide substances to a mass spectrometer. The microfluidic devices include first and second surfaces, at least one microchannel formed by the surfaces, and an outlet at an edge of the surfaces. Some embodiments also include a tip surface with one or more surface features for helping guide substances from the outlet of the device toward a mass spectrometer. In some embodiments, the surface feature(s) includes a groove, which may be hydrophilic along all or part of its length. Hydrophilic surfaces and/or hydrophobic surfaces may also help guide substances out of the outlet and/or toward the mass spectrometer. In some embodiments, the outlet and/or the tip surface is recessed back from an adjacent portion of the edge. A source of electrical potential can help move substances through the microchannel, separate substances and/or provide electrospray ionization.

    摘要： An infusion pump (e.g., an electrokinetic infusion pump) includes an infusion pump module and an engine that can drive a moveable piston non-mechanically. In addition, the infusion pump module includes a position detector configured for sensing a dispensing state of the infusion pump module. Such information can be utilized in a control scheme to control fluid displacement within and out of the pump. Descriptions of different types of position detectors, such as magnetic sensors (e.g., an anisotropic magnetic resistive sensor), and their implementation in detecting infusion pump fluid displacement are described.

    摘要： A microfluidic chip formed with multiple fluid channels terminating at a tapered electrospray ionization tip for mass spectrometric analysis. The fluid channels may be formed onto a channel plate that are in fluid communication with corresponding reservoirs. The electrospray tip can be formed along a defined distal portion of the channel plate that can include a single or multiple tapered surfaces. The fluid channels may terminate at an open-tip region of the electrospray tip. A covering plate may substantially enclose most portions of the fluid channels formed on the channel plate except for the open-tip region. Another aspect of the invention provides methods for conducting mass spectrometric analysis of multiple samples flowing through individual fluid channels in a single microfluidic chip that is formed with a tapered electrospray tip having an open-tip region.
