Abstract:
An apparatus for optical measurement of a liquid or molten material, which has: a transparent container which has a bottom face and is capable of containing a to-be-measured material therein, with the bottom face at least having a flat face and being transparent; and an optical device that irradiates a light to the bottom face of the container and that detects and measures a reflected light from the bottom face; and a method for optically measuring a liquid or molten material using the apparatus.
Abstract:
An analysis method includes the steps of causing a moist sample to react with a reagent and measuring concentration of a particular component contained in the sample based on the state after the reaction of the sample with the reagent. The reaction step and the measurement step are performed while the amount of moisture contained in the air in a space accommodating the sample and the reagent is directly or indirectly measured. The method further includes the step of correcting the measurement result of the concentration of the particular component based on the amount of moisture contained in the air.
Abstract:
The present invention provides miniaturized instruments for conducting chemical reactions where control of the reaction temperature is desired or required. Specifically, this invention provides chips and optical systems for performing and monitoring temperature-dependent chemical reactions. The apparatus and methods embodied in the present invention are particularly useful for high-throughput and low-cost amplification of nucleic acids.
Abstract:
The present invention relates to a photometric device for measuring optical parameters. The invention functions in the ultraviolet light range through use of a monochromator and splits the test light in multiple channels by a rotor assembly, including a mirror.
Abstract:
A chemiluminescence analyzer determines the level of chemiluminescence of a specimen. The chemiluminescence analyzer includes a light detection chamber for containing the specimen to be analyzed. The light detection chamber includes a chamber access device, for allowing the positioning of the specimen within the light detection chamber, and a shutter device. The shutter device and the chamber access device are configured to each have an open position and a closed position. A light detector is positioned behind the shutter device. When the shutter device is in the open position, the light detector detects light within the light detection chamber. An interlock assembly is interfaced with the shutter device and the chamber access device, such that the interlock assembly prevents the shutter device and the chamber access device from being simultaneously opened.
Abstract:
An oxygen sensor contains an indicator whose change in absorption is a function of the concentration of oxygen in a sample bathing the indicator. Light transmitted and reflected through the indicator of the sensor undergoes an absorption that is characteristic of the concentration of oxygen. The indicator is a viologen whose absorption returns to a steady-state value after it has been subjected to a pulse of short-wavelength light. The rate at which the absorption returns to the steady-state value is a function of the concentration of oxygen bathing the viologen indicator. A measurement system for use with the pO.sub.2 sensor causes a short-wavelength flash to be sent to the sensor and thereafter monitors the time-varying absorption of the sensor to measure the oxygen content of the sample bathing the viologen indicator.
