  • Patent number: 10976289
    Abstract: To determine a corrected flow rate value of a mobile phase flowing in a liquid chromatography (LC) system, a flow rate of the mobile phase at a selected reference position in the LC system is measured to produce one or more flow rate values. A model of the LC system is applied to the flow rate value(s) to determine the corrected flow rate value(s). The model includes a distribution of capacitive elements and resistive elements arranged according to a topology of the LC system. The capacitive and resistive elements are representative of system and solvent properties affecting flow rate while operating the LC system. The system and solvent properties may be properties affecting the flow rate while operating the LC system under dynamic conditions.

  • Publication number: 20210074534
    Abstract: A system and method for detecting energetic particles include a detector onto which the particles are impinged. An output signal from the detector, indicative of the energy of the particles, is directed by an AC-coupler to a measurement device to determine particle characteristics such as mass and/or abundance. The detector is selectively couplable to positive or negative bias voltages, and in one embodiment is differentially biased to eliminate ringing due common-mode excitation. The AC-coupler has capacitively-coupled input and output terminals that are embedded in a transmission line structure including capacitances that in some embodiments serve as the sole energy storage component in order to reduce the effects of parasitic inductance found in conventional detection circuits. In some embodiments, a pulse compensation network is provided, to reduce undershoot and ringing due to remote installation of the AC-coupler caused by reflection of low frequency components blocked by the AC-coupler.

  • Patent number: 10942176
    Abstract: Provided herein are methods of using photocleavable labels for multiplex and serial antigen detection. The methods comprise detecting the presence of photocleavable labels, which are conjugated through functional linkers to antigen-binding complexes, which in turn non-covalently bind to antigens. The presence of a photocleavable label is indicative of the presence of an antigen specifically or selectively bound by an antigen-binding complex. Also provided are apparatuses for using photocleavable labels for multiplex and serial antigen detection.

  • Patent number: 10914658
    Abstract: The present disclosure is directed to an improved method for distinguishing tissue from an embedding medium, such as paraffin in a formalin-fixed paraffin-embedded sample. The method involves the use of fluorescence of naturally-occurring species in tissue to determine the location of the tissue in the embedded sample. An embedded sample is generally excited by light of a selected wavelength, and the fluorescence emission at an emitted wavelength is used to locate the boundary or location of the tissue in the embedded sample.
