摘要： A system (e.g., a chromatography system) includes a rotor, a microfluidic device, a rotor driver, a clamping mechanism, and control electronics. The rotor defines a plurality of first fluid-conveying features. The micro fluidic device defines one or more channels and a plurality of second fluid-conveying features, in fluid communication with the one or more channels. The rotor driver is coupled to the rotor and is configured to rotate the rotor, relative to the microfluidic device, between a first position and a second position such that, in each of the positions, at least one of the first fluid-conveying features cooperates with at least one of the one or more channels to provide for fluid communication therebetween. The clamping mechanism is operable to provide a sealing force to establish a fluid-tight seal between the rotor and the microfluidic device.

摘要： An apparatus for use in a chromatography system includes a microfluidic substrate having a fluidic channel configured as an analytical chromatographic column and a fluidic port on one side of the microfluidic substrate. The fluidic port opens at a head end of the analytical chromatographic column. A dried blood spot (DBS) collection device holds one or more dried biological samples. The DBS collection device is directly coupled to the microfluidic substrate whereby one of the biological samples is placed into fluidic communication with the fluidic channel of the microfluidic substrate and an extraction of that biological sample flows toward the head end of the analytical chromatographic column. A diluent source fluidically coupled to the fluidic port supplies a solvent to the head end of the analytical column to dilute the extracted biological sample before the biological sample flows into the analytical chromatographic column.

摘要： An electrokinetic pump can be used to deliver calibrant ("lock mass") ions to a mass spectrometer for calibration of a mass spectrometry system. Electrokinetically controlled calibrant delivery can help to eliminate the need for the more cumbersome mechanisms that are often used for ion delivery. In addition, electrokinetically controlled calibrant delivery can provide for a more user- friendly system in which a calibrant solution can be packaged into a disposable cartridge. Furthermore, when implemented in a microfluidic format, electrokinetically controlled calibrant delivery can be coupled with an electrokinetically controlled separation system, such as capillary electrophoresis (CE), to allow efficient solid-state switching between analytical and calibrant sprays.

摘要： Variable- volume injection valves include a stator and a rotor. The stator has a first port, a second port, and a contact surface with a groove therein. The first port opens into the stator groove. The rotor has a contact surface with a groove therein. The contact surface of the rotor is urged against the contact surface of the stator such that the rotor groove opposes the stator groove with one end of the rotor groove overlapping the stator groove and the opposite end of the rotor groove overlapping the second port of the stator. The overlapping grooves of the rotor and stator provide a fluidic channel between the first and second ports of the stator. The rotor is movable with respect to the stator in order to vary a length of overlap between their overlapping grooves.
