  • Patent number: 9952134
    Abstract: An analytical instrument for cellular analysis of cellular particles tagged with elemental tags, such as lanthanide-based elemental tags. The analytical instrument has a sample introduction system for generating a stream of particles from the sample. An inductively coupled plasma ionization system atomizes and ionizes particles in the stream as they are received. The instrument has an ion pretreatment system and a mass analyzer. The ion pretreatment system is adapted to transport ions generated by the ionization system to the mass analyzer. The ion pretreatment system can filter out low mass ions, such as using a high-pass mass filter or a bandpass mass filter, to allow the elemental tags to pass therethrough. The mass analyzer is adapted to measure the amount of at least one element in individual particles from the stream by performing mass analysis on the ions from the atomized particles.

  • Patent number: 9945787
    Abstract: An optical device for determining the presence and/or concentration of analytes in a sample is presented. The optical device comprises a detector and a detection unit comprising optical path components. The detection unit has wavelength-dependent responsivity. The optical device further comprises a light source for emitting light of different respective usable wavelength ranges. The light is guidable through the optical path to the detector to generate baseline signals and response signals relative to the baseline signal indicative of the presence and/or concentration of analytes in the optical path. The intensity of the light reaching the detector is adjusted inverse to the wavelength-dependent responsivity with respect to at least two respective usable wavelength ranges so that a reduction of the ratio between the maximum baseline signal at one of the selected usable wavelength ranges and the minimum baseline signal at another of the selected usable wavelength ranges is obtained.

  • Patent number: 9947519
    Abstract: Based on the m/z of a precursor ion used in an MS2 analysis of a test sugar chain, a plurality of sugar-chain structure candidates are extracted from a sugar-chain database in which various sugar-chain structures are related to m/z (S2). Product ions that can be generated by cutting one sugar-chain bond are calculated for each sugar-chain structure candidate (S3). For each combination of two sugar-chain structure candidates, the product ions of one candidate are compared with those of the other to extract characteristic product ions for each sugar-chain structure candidate, and their m/z values are calculated (S4). Whether or not an MS2 spectrum of the test sugar chain has a peak located at m/z of any of the characteristic product ions is determined, and based on the determination result, the sugar-chain structure candidates are narrowed down (S5) and the obtained result is shown on a display unit (S6).

  • Patent number: 9920020
    Abstract: Squaraine dyes are used to detect the presence of protein in a test sample, which is a substance that may contain protein. A squarine dye is placed in water, and in some instances joined with an aggregation agent, to create an aqueous dye solution. That dye solution is joined with a test sample. When the dye solution is joined with the test sample and the resultant test solution is excited by the application of photons, a resulting fluorescence or absence thereof reveals if protein was present in the test sample.

  • Patent number: 9878326
    Abstract: The direct integration of light and optical control into microfluidic systems presents a significant hurdle to the development of portable optical trapping-based devices. A simple, inexpensive fiber-based approach is provided that allows for easy implementation of diode-bars for optical particle separations within flowing microfluidic systems. Models have also been developed that demonstrate the advantages of manipulating particles within flow using linear geometries as opposed to individually focused point traps as traditionally employed in optical-trapping micromanipulation.
