  • Publication number: 20200126778
    Abstract: Methods, systems and devices that generate differential axial transport in a fluidic device having at least one fluidic sample separation flow channel and at least one ESI emitter in communication with the at least one sample separation flow channel. In response to the generated differential axial transport, the at least one target analyte contained in a sample reservoir in communication with the sample separation channel is selectively transported to the at least one ESI emitter while inhibiting transport of contaminant materials contained in the sample reservoir toward the at least one ESI emitter thereby preferentially directing analyte molecules out of the at least one ESI emitter. The methods, systems and devices are particularly suitable for use with a mass spectrometer.

  • Patent number: 10572467
    Abstract: Techniques for providing feed-based case management on an online social network. A user interface that includes a publisher and an information feed is provided. Information associated with a record is received and the record is updated in a database system. A feed item associated with the database system update is generated and provided in the information feed. The feed item includes one or more actionable selections providing a reference to the publisher. Selection of one of the one or more actionable selections causes the publisher to be operable to receive further information associated with the record. The record is capable of being updated based on the further information. In some implementations, the record is a case and the user interface serves as a single interface for all interactions required in solving the case.

  • Patent number: 10571428
    Abstract: Devices and methods generate an ordered restriction map of genomic DNA extracted from whole cells, nuclei, whole chromosomes, or other sources of long DNA molecules. The devices have a fluidic microchannel that merges into a reaction nanochannel that merges into a detection nanochannel at an interface where the nanochannel diameter decreases in size by between 50% to 99%. Intact molecules of DNA are transported to the reaction nanochannel and then fragmented in the reaction nanochannel using restriction endonuclease enzymes. The reaction nanochannel is sized and configured so that the fragments stay in an original order until they are injected into the detection nanochannel. Signal at one or more locations along the detection nanochannel is detected to map fragments in the order they occur along a long DNA molecule.

  • Patent number: 10471428
    Abstract: Fluidic devices with a primary transport nanochannel(s) intersected by at least one nanoscale manifold for active control of capture, manipulation and transport of analyte molecules. The at least one manifold can be an array or network of nanochannels, nanoslits or nanoelectrodes joined to a common voltage or pressure source. A respective nanoscale manifold can be configured to allow for precise and active control of driving forces applied to the primary transport nanochannel(s) to drive molecular transport through the various regions along the transport nanochannel(s). The at least one manifold can generate monotonic force gradients with a limited or reduced number of independent input potentials and/or pressures applied to the device.

  • Publication number: 20190287781
    Abstract: An electrospray ionization (ESI)-mass spectrometer analysis systems include an ESI device with at least one emitter configured to electrospray ions and a mass spectrometer in fluid communication with the at least one emitter of the ESI device. The mass spectrometer includes a mass analyzer held in a vacuum chamber. The vacuum chamber is configured to have a high (background/gas) pressure of about 50 mTorr or greater during operation. During operation, the ESI device is configured to either; (a) electrospray ions into a spatial region external to the vacuum chamber and at atmospheric pressure, the spatial extent being adjacent to an inlet device attached to the vacuum chamber, the inlet device intakes the electrosprayed ions external to the vacuum chamber with the mass analyzer and discharges the ions into the vacuum chamber with the mass analyzer; or (b) electrospray ions directly into the vacuum chamber with the mass analyzer.

  • Patent number: 10403488
    Abstract: Methods, systems and devices that provide fluid devices with at least one SPE bed adjacent (upstream of) a separation channel which may be in communication with an inlet of a Mass Spectrometer. The fluid device can be configured to operate using independently applied pressures to a BGE reservoir and a sample reservoir for pressure-driven injection that can inject a discrete sample plug into a separation channel that does not require voltage applied to the sample reservoir and can allow for in-channel focusing methods to be used. The methods, systems and devices are particularly suitable for use with a mass spectrometer but optical or other electronic detectors may also be used with the fluidic devices.

  • Publication number: 20190221414
    Abstract: A miniature electrode apparatus is disclosed for trapping charged particles, the apparatus includes, along a longitudinal direction, a first end cap electrode, a central electrode having an aperture, and a second end cap electrode. The aperture is elongated in the lateral plane and extends through the central electrode along the longitudinal direction and the central electrode surrounds the aperture in a lateral plane perpendicular to the longitudinal direction to define a transverse cavity for trapping charged particles. Electric fields can be applied in a y-direction of the lateral plane across one or more planes perpendicular to the longitudinal axis to translocate and/or manipulate ion trajectories.
