Abstract:
Measuring device (1; 15) for determining the composition of the liquid phase of a liquid-gas mixture, comprising a duct (2) defining a flow direction (X) of the mixture parallel to the longitudinal development axis (Y) of the duct (2) and a measuring element (4) arranged in the duct (2) and suited to determine the composition of a liquid layer that flows in contact with the internal surface (3) of the duct (2). The internal surface (3) of the duct (2) comprises an intercepting surface (5, 5') suited to convey part of the liquid layer towards the measuring element (4), arranged so that it is incident on the flow direction (X) and developed according to a conveyance trajectory that has a helical section and whose tangent to the outlet end (7, 7') intersects the measuring element (4).
Abstract:
An automatic optical measurement system (100) is provided. The measurement system (100) includes a sample vial (10) and an automatic optical measurement apparatus (90) configured to receive the sample vial (10). The automatic optical measurement apparatus (90) is configured to detect a presence of the sample vial (10) in the automatic optical measurement apparatus (90) and measure a light intensity of light substantially passing through the sample vial (10) if the sample vial (10) is present. The measured light intensity is related to sample material properties of a sample material within the sample vial (10).
Abstract:
Un procédé et un appareil permettent d'effectuer rapidement des analyses concernant l'or, par exemple dans des échantillons de sols ou de roches. Il convient de mettre la solution contenant de l'or en contact avec un agent d'oxydation et au moins un éther couronné, puis de séparer le complexe or-éther couronné des composants restants de la solution ; on récupère alors les ions d'or dans le complexe or-éther couronné puis on met la solution résultante contenant de l'or en contact avec un agent de marquage tel qu'un chromophobe, après quoi on mesure la quantité d'agent de marquage lié qui se trouve dans la solution. L'appareil (10, 11) comprend une source optique (14) qui illumine le complexe échantillonné (12) avec un rayonnement incident sur une première longueur d'onde, un détecteur (20) qui détecte la lumière rendue fluorescente sur une deuxième longueur d'onde, un détecteur (21) qui détecte la lumière transmise sur cette première longueur d'onde, et un détecteur (15) qui détecte l'intensité du rayonnement de la source. Un processeur (46) corrige la lumière détectée rendue fluorescente, et la lumière trsnsmise, des variations d'intensité relatives au rayonnement incident et détermine séparément la teneur en or sur la base de la lumière détectée rendue fluorescente et de la lumière émise, telles que respectivement corrigées, et choisit celle des deux mesures qui représente le plus fidèlement la teneur en or.
Abstract:
Disclosed herein is a reflected light measuring instrument for receiving reflected light from an object under measurement, which has an effect that even if a reflection surface of the object under measurement shifts in position in the direction of an optical axis, a quantity of reflected light at the reflection surface is automatically corrected to be substantially constant, whereby the read accuracy on said reflection surface is not lowered at all.
Abstract:
A measuring apparatus of the present invention measures the constituent concentration of a specimen after loading into the apparatus a test piece having a test material which develops coloring as a result of a reaction with the constituents of a specimen. When the apparatus detects that the test piece having the test material has been loaded, it automatically begins to measure the constituent concentration of the specimen. That is. after the loading of the test piece is detected, a predetermined time period is measured. During this time measurement, the time period is displayed at a predetermined time interval. After the time measurement of this predetermined time period is terminated, the test material is irradiated with a light, and the intensity of the light from the test material is detected. The constituent concentration of the specimen applied to the test material can be determined on the basis of the reflected light intensity thus detected. Furthermore, this measuring apparatus can detect a reverse insertion of a test piece, and is constructed so as to disable the measurement of the constituent concentration of a specimen if supplementary information to be stored along with measurement information has not been set.
Abstract:
Improved sub-assemblies and methods of control for use in a diagnostic assay system adapted to receive an assay cartridge are provided herein. Such sub-assemblies include: a brushless DC motor, a door opening/closing mechanism and cartridge loading mechanism, a syringe and valve drive mechanism assembly, a sonication horn, a thermal control device and optical detection/excitation device. Such systems can further include a communications unit configured to wirelessly communicate with a mobile device of a user so as to receive a user input relating to functionality of the system with respect to an assay cartridge received therein and relaying a diagnostic result relating to the assay cartridge to the mobile device.
Abstract:
A configuration of detecting light from the front face of a light source is the best for confirming the variation of a light quantity, but when a plurality of light sources are present, as many detectors for checking a light quantity as the light sources are necessary and the apparatus configuration becomes complex. In the present invention, a detector 130 for checking a light source light quantity is installed in a reaction container transfer mechanism 117 used commonly for a plurality of detection sections, and the light quantities of light sources 124 are checked with the detector 130.
