  • Patent number: 11181446
    Abstract: A method and system for sampling a solid sample material can include the step of mounting the sample material on a support. A sample surface is coated with a surface treatment composition in a dry deposition process. A solvent supply conduit for supplying solvent to the sample surface and a solvent exhaust conduit for withdrawing solvent from the sample surface can be provided. Solvent is flowed from the solvent supply conduit to the surface treatment composition and the sample surface such that the solvent contacts the surface treatment composition. A laser beam is directed from a laser source to the sample and the surface treatment composition. The laser beam will ablate the sample and the surface treatment composition in portions intersected by the laser beam. Ablated sample material enters the solvent liquid and will be transported with the solvent away from the sample surface through the solvent exhaust conduit.

  • Patent number: 11105722
    Abstract: Certain implementations of the subject matter can be implemented to screen demulsifiers. A live emulsion of a live hydrocarbon sample and a water sample is flowed through a capillary viscometer. The live hydrocarbon sample includes dissolved gases retrieved from a hydrocarbon-carrying reservoir. While flowing the live emulsion through the capillary viscometer, a demulsifier sample is flowed through the capillary viscometer. The demulsifier sample is capable of causing breakdown of the live emulsion. Using the capillary viscometer, change in a viscosity of the live emulsion over time resulting from the breakdown of the live emulsion due to the demulsifier sample is measured. Multiple images of the breakdown of the live emulsion over time are captured. A strength of the live emulsion is classified based, in part, on the change in the viscosity of the live emulsion over time and on the plurality of images.

  • Patent number: 9736555
    Abstract: A method for cross-talk correction of intensities measured on mutually separate detection wavelength bands is presented. Each detection wavelength band relates to one of analyte-specific probe-populations contained by a sample to be analyzed. Each probe-population is capable of emitting a first signal component and a second signal component whose spectra have maxima at different wavelengths and at least the first signal component is dependent on presence of analyte detectable with that probe-population. Cross-talk corrected intensities are computed on the basis of a) the intensities measured on the detection wavelength bands, b) a value indicative of intensity occurring on an auxiliary wavelength band outside the detection wavelength bands and at least partially caused by the second signal components, and c) pre-determined cross-talk parameters.

  • Patent number: 9707555
    Abstract: Methods and devices are provided for pretreatment of a sample containing microbial cells. In some embodiments, the pretreatment of the sample is performed via the initial selective lysis, within a sample pretreatment vessel, of non-microbial cells (such as blood cells) and the subsequent centrifugal separation of the sample to remove the resulting debris and concentrate the microbial cells. An immiscible and dense cushioning liquid may be included for collecting the microbial cells adjacent to the liquid interface formed by the cushioning liquid upon centrifugation of the pretreatment vessel. After removal of a substantial quantity of the supernatant, resuspension of the collected microbial cells, and re-establishment of the cushioning liquid interface, at least a portion of the remaining suspension may be removed without substantially removing the cushioning liquid. One or more intermediate wash cycles may be performed prior to extraction of the remaining suspension, which provides a “pretreated” sample.

  • Patent number: 9638695
    Abstract: A non-invasive method of detecting or screening for lung cancer in a subject specimen is provided. The method includes detecting elevated levels of one or more carbonyl-containing volatile organic compounds (VOCs) that are biomarkers for lung cancer in exhaled breath from the subject specimen. The method may further include obtaining exhaled breath from the subject specimen; forming adducts of the carbonyl-containing VOCs with a reactive chemical compound; quantifying the adducts of the carbonyl-containing VOCs to establish a subject value for each of the adducts; and comparing each subject value to a threshold healthy specimen value for each of the adducts of the carbonyl-containing VOCs. One or more subject values at quantities greater than threshold healthy specimen values are also useful for screening for lung cancer in the subject specimen.

  • Patent number: 9606126
    Abstract: The invention provides methods to assess protein stability and to obtain sizing information. In one aspect, the screen comprises a 94 detergent panel and a series of MWCO filtered microplates. A protein of interest is bound to an affinity matrix and aliquoted into a 96-well microplate. Wells containing the immobilized protein are washed in the new detergent and then eluted in the new detergent into a collection plate. Protein not stable in the new detergent is precipitated on the resin and not present in the elutions. Half of the elution is passed through a high (i.e., 300 kDa) MWCO microplate and the other half through a low (i.e., 100 kDa) MWCO microplate. Elutions from the microplates are spotted on a nitrocellulose membrane, visualized by Western analysis (or by some other method), and quantified. The high MWCO provides stability readout and the ratio of low/high kDa provides sizing information.

  • Patent number: 9526745
    Abstract: Embodiments of the present invention relate to methods for preparing high optical density solutions of nanoparticle, such as nanoplates, silver nanoplates or silver platelet nanoparticles, and to the solutions and substrates prepared by the methods. The process can include the addition of stabilizing agents (e.g., chemical or biological agents bound or otherwise linked to the nanoparticle surface) that stabilize the nanoparticle before, during, and/or after concentration, thereby allowing for the production of a stable, high optical density solution of silver nanoplates. The process can also include increasing the concentration of silver nanoplates within the solution, and thus increasing the solution optical density.

  • Patent number: 9067167
    Abstract: The present invention refers to a modulator, to be used for comprehensive multidimensional chromatography separations, to entrap and release sample solute fractions (entrapped in a capillary loop of fixed or variable volume), deriving from a capillary column with an internal diameter ranging from 0.01 mm to 0.53 mm, onto another capillary column with an internal diameter ranging from 0.01 mm to 0.53 mm. The micro-device has been integrated in a gas chromatographic system, composed of two ovens for the independent temperature control of the two columns; the micro-device is characterized, internally, by a system of channels that enable the controlled splitting of gas flow, entering the second capillary, to generate an optimum gas linear velocity and to release the pressure in excess, with the objective of attaining the maximum separation efficiency in the second column.

  • Patent number: 9063158
    Abstract: An HPLC module utilizes a combination of compound-dedicated hardware providing line clearance between differing radiosynthesis and includes multiple compound-dedicated HPLC inject valves, each inject valve directing a fluid to a serially-connected HPLC column and UV flowcell so as to prevent cross-contamination between differing radiopharmaceutical syntheses. The module provides a disposable fluid path from each UV flowcell allowing for radioactive detection, fraction collection, formulation and final product dispensing. In this manner, a level of GMP compliance is achieved that is suitable for meeting the requirements of an MHRA approved site-license.
