Abstract: First, an analytical chip having a prism, a metal film that includes a trapping region having immobilized on the surface thereof a trapping element for trapping a substance to be analyzed, and a mark in which the scatter of emitted plasmon scattered light differs from the scatter of plasmon scattered light emitted from the surrounding region, is disposed in a chip holder. Next, the rear surface of the metal film is irradiated with excitation light, plasmon scattered light emitted from the proximity of the mark is detected, and, on the basis of the detected plasmon scattered light, location information for the trap region is obtained. Next, the portion of the rear surface of the metal film that corresponds to the trap region arranged at the detected location is irradiated with excitation light, and fluorescence emitted by a fluorescent substance is detected.

Abstract: In the present invention, excitation light is irradiated onto an analysis chip that has been placed in a chip holder, reflected light or transmitted light from the analysis chip is detected, and as a result the position information of the analysis chip is obtained. On the basis of this position information, the chip holder is moved by a conveyance stage and thereby moved to a measurement position. Excitation light is irradiated onto the analysis chip that is disposed at the measurement position, and fluorescence emitted from a fluorescent substance that marks the substance to be detected is detected.

Abstract: This specification discloses an ophthalmologic apparatus for executing an eye examination on an eye to be examined. The ophthalmologic apparatus is provided with an eye examination unit, an alignment drive system for driving the eye examination unit to thereby execute the alignment between the eye examination unit and the eye to be examined, a time measuring portion, and a control system for causing the alignment drive system to drive the eye examination unit on the basis of the output of the time measuring portion so as to return the eye examination unit to an eye examination waiting position.

Abstract: An ophthalmologic apparatus can measure the eye axis length of an eye to be examined and other information of the eye to be examined (for example, the cornea refractive power). In the case of the measurement of the eye axis length, when moving a detecting terminal itself by driving means, the driving means is controlled so as to slow down the speed of movement of the detecting terminal when the detecting terminal comes near the cornea of the eye to be examined.

Abstract: A supersonic ophthalmic measuring apparatus includes a supersonic probe for contacting the cornea of an eye to be examined. A calculator for calculating the amount of depression of the cornea of the eye to be examined caused by the supersonic probe, and a corrector for correcting the result of the measurement of the eye axis length of the eye to be examined by the supersonic probe by the amount of depression.

Abstract: An ophthalmic measuring apparatus has an ultrasonic detector for measuring the length of a predetermined region of an eye to be examined, a device provided with a center axis coaxial with the center axis of the vibrator of the ultrasonic detector and projecting an index mark onto the cornea of the eye to be examined, and an imaging optical system for forming the corneal reflection image of the index mark on a predetermined image plane to measure the shape of the cornea.

Abstract: In a method of analyzing a sample by measuring retention time of the components of the sample, a method of ananlysis by chromatogram which displays schematic chromatograms related to particular fillers and particular object components to be analyzed, relying upon the retention time and half widths of various object components to be analyzed that have been stored and are related to various fillers to be charged into the separation column. The invention further deals with a chromatogram analysis apparatus comprising means which stores the retention time and half widths of objects components to be analyzed related to various fillers that are to be charged into the separation column, and means which prepares schematic chromatograms related to particular fillers. Schematic chromatograms are displayed to efficiently and quickly select a filler that is suited for the analysis of saccharide. The apparatus for analysis can be used independently, or as a component of the chromatograph data processor.

Abstract: A definite, but large amount of a sample solution is fed to a small concentration column filled with a packing material to retain in the concentration column components to be measured in the sample solution. Then, a small amount of a desorbing solution is fed to the concentration column to desorb the components retained in the concentration column. The effluent solution containing the desorbed components is fed to a separation column filled with a packing material. An eluting solution is fed to the separation column to separate the components from one another, and the components are detected by a detector.Since the components are separated from one another after their concentrations have been elevated, and thus the components can be measured with a high sensitivity.
