  • Patent number: 11047857
    Abstract: An immunoassay test slide for use in a dry chemistry analytical instrument includes a slide housing or case formed from two matable sections—a slide cover piece and a slide bottom piece. The slide housing defines an interior cavity in which is situated a sheet-like porous carrier matrix. The slide cover piece has an opening formed through the thickness thereof to expose a central portion of the fluid flow matrix so that a precise volume of fluid sample of blood, serum or the like, preferably pre-mixed with a conjugate reagent, and precise volumes of a wash reagent and a substrate (detector reagent), may be deposited on the matrix through the cover opening by a metering device of the analytical instrument. The bottom piece of the immunoassay test slide is transparent, and the slide is moved by a transport mechanism of the analytical instrument over a reflectometer or a fluorometer for performing reflectance or fluorescence measurements.

    Abstract: Provided is a measuring chip, a measuring device and a measuring method, which are capable of performing a more simple and highly accurate measurement than the conventional measurement. Light introduced into an incoming part may propagate while totally reflecting within a propagating part of a propagation layer. A phase shift amount in the total internal reflection may be different between sections of an upper surface of the propagation layer where a ligand is formed and where a ligand is not formed. When an analyte is adsorbed to the ligand, the phase shift amount in the reflection may become larger than before attaching the analyte. As a result, a beam pattern of the light outputted from an outgoing part may change.

  • Patent number: 10552965
    Abstract: The atomic absorption spectrophotometer is provided with an atomization unit, a light source, a detector, an optical system, a camera, and a captured image data storage unit. The atomization unit has a tube-like furnace and atomizes the sample injected into the furnace by heating the sample. The light source emits light of a wavelength of a measurement target toward the atomization unit so that the light passes through the furnace. The detector detects the light passed through the furnace. The camera captures an image of an inside of the furnace before performing a measurement process in which a sample is atomized in the furnace and its absorbance is measured. The captured image data storage unit stores the captured image data obtained by capturing the image by the camera in association with the measurement data corresponding to the captured image data.

  • Patent number: 10539776
    Abstract: Disclosed herein are systems for imaging of samples using an array of micro optical elements and methods of their use. In some embodiments, an optical chip comprising an array of micro optical elements moves relative to an imaging window and a detector in order to scan over a sample to produce an image. A focal plane can reside within a sample or on its surface during imaging. Detecting optics are used to detect back-emitted light collected by an array of micro optical elements that is generated by an illumination beam impinging on a sample. In some embodiments, an imaging system has a large field of view and a large optical chip such that an entire surface of a sample can be imaged quickly. In some embodiments, a sample is accessible by a user during imaging due to the sample being exposed while disposed on or over an imaging window.

    Abstract: Disclosed is a combination of a Fabry-Perot Tunable Filter (FPTF) wavelength selector, an internal reflection element (IRE) capable of measuring Attenuated Total Reflectance (ATR) spectra, and a pressure application element for applying pressure to samples, if needed. The resultant portable and compact device is called an FPTF-ATR spectrometer. The device measures data that can be used to identify chemical species in samples, predict properties of samples, and quantify amounts of chemical species in samples. Also disclosed are methods for using the FPTF-ATR for analyzing samples, especially analyzing compounds containing cannabis, hops, and other chemical species where portable chemical analysis is important.
