Abstract:
The scattered light from the measurement target substance passes through a light receiving window, and is received by a detector for +θ scattered light and a detector for −θ scattered light which are arranged symmetrically to each other across an optical axis at an equal angle or an equal interval in a vertical direction. A light source is fixed by a light-source holder (that is a base member on which the light source is arranged), and the detectors are arranged on and fixed to a detector holder (that is a base member on which the detectors are arranged). In this manner, drift of the light quantity data caused by the thermal deformation of the optical system can be corrected by comparing values of the light quantity data of the detectors.
Abstract:
A test tape device is disclosed herein for use with a replaceable analytical tape cassette, where the device includes a housing having a cassette compartment covered by a cassette door and a housing opening for sample application, a protective cover that can be moved between a closed position covering the housing opening and a release position allowing access to the housing opening and a door lock for retaining the cassette door in the closed position, wherein the protective cover is coupled with the door lock via an interlocking mechanism, such that the door lock can only be unlocked in the release position of the cover.
Abstract:
An automated analyzer for performing multiple diagnostic assays simultaneously includes multiple stations in which discrete aspects of the assay are performed on fluid samples contained in sample vessels. The analyzer includes stations for automatically preparing a sample, incubating the sample, preforming an analyte isolation procedure, ascertaining the presence of a target analyte, and analyzing the amount of a target analyte. An automated receptacle transporting system moves the sample vessels from one station to the next. A method for performing an automated diagnostic assay includes an automated process for isolating and amplifying a target analyte, and, in one embodiment, a method for real-time monitoring of the amplification process.
Abstract:
A surface plasmon resonance measuring apparatus is provided with a dielectric block, a metal film formed on a surface of the dielectric block, a light source for emitting a light beam, an optical system for making the light beam enter the dielectric block at various angles of incidence so that a condition for total internal reflection is satisfied at an interface between the dielectric block and the thin film layer, and a photodetector for detecting the intensity of the light beam satisfying total internal reflection at the interface. In the measurement chip to be utilized in the surface plasmon resonance measuring apparatus, the dielectric block is formed from a synthetic resin in which, when said light beam is p-polarized outside said dielectric block and then strikes the interface, the intensity of a s-polarized component at the interface is 50% or less of the intensity of the light beam at the interface.
Abstract:
According to one embodiment, an automatic analyzer comprises a light source, a spectroscope, a photo detection unit, a storage unit, a selection unit, and a calculation unit. The storage unit stores photo detector identifiers related to photo detectors and wavelength band identifiers in association with each other. The selection unit selects a specific photo detector from photo detectors. The specific photo detector corresponds to a specific photo detector identifier associated with a wavelength band identifier of a wavelength band according to a measurement item of a sample. The calculation unit calculates an absorbance related to the measurement item based on a signal from the selected specific photo detector.

Abstract:
A method and device for enhancing the power correction of optical measurements in an optical measurement arrangement, the steps including: providing a light source for producing a light beam; splitting the light beam into two beams; directing a first split light beam through an interrogation area and into an optics separation device; directing the light beams from the optics separation device and a second split light beam representing the intensity of the illumination of the main light beam of the light source into cells of a detector array; measuring and assessing the information obtained in the cells; and using this information to calculate the corrected value for the cells receiving the light beams from the optics separation device in order to adjust the power for the intensity of the light beam of the light source and/or to correct the intensity of the light beams from the interrogation area.
