Abstract:
Provided is a weak luminescence detecting device that is capable of, in luminescence measurements, reducing dark current values and dark current pulse counts, preventing fluctuations in dark current values and dark current pulse counts with respect to temperature, and capturing an optical signal with a large solid angle, and that can, with high sensitivity, detect luminescence without directivity, such as bioluminescence and chemiluminescence. A luminescence measuring device is provided with a plate member to hold a container holder in which a sample is stored, a light detector to detect luminescence in the sample, a temperature control unit to control the temperature of the light detector, and a ventilator to blow air on the light receiving face of the light detector.
Abstract:
In a method for performing a refractive index based measurement of a property of a fluid such as chemical composition or temperature, a chirp in the local spatial frequency of interference fringes of an interference pattern is reduced by mathematical manipulation of the recorded light intensity in the interference pattern or by the physical positioning and arrangement of a detector used for capturing the interference pattern.

Abstract:
An automatic analyzing apparatus which can make an adjustment to a target temperature so as to stabilize the light intensity of an LED and also can make the adjustment to that temperature in a short time is provided. The automatic analyzing apparatus in which an LED is used for a light source 114 includes a temperature adjusting mechanism 201 for the LED, and the temperature adjusting mechanism 201 includes a metal member 202 provided with the light source 114, a pair of metal pipes (water-flowing pipes) 203 buried in the metal member 202 and allowing constant-temperature bath water to flow therein, and pins (small metal piece members) 204 bringing only a heat-generating lead 252 of the light source 114 into direct contact with the metal member 202. Therefore, the temperature adjusting mechanism 201 can make an adjustment to a target temperature so as to stabilize the light intensity of the LED, and the adjustment to that temperature can be made in a short time.

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.
