摘要： The adverse effect on measurement accuracy brought about by the transmission of light beams through portions of a liquid sample with different concentrations, i.e., a concentration distribution in the vertical direction of a container, is prevented by using semiconductor light sources of two different types with different wavelengths. The semiconductor light sources (2, 4) of two different types are housed in the same package (5) such that a detector (9) can capture the light beams emitted by the light sources after their optical axes have intersected with one another. The multiple light beams can be thus caused to pass through portions with substantially the same concentration and therefore can be detected without being influenced by the difference in concentration of the sample in the container.

摘要： Conventional liquid transport substrates having a fluid channel formed along an array of electrodes have a problem in which throughput decreases, depending on driving conditions. In order to avoid two-way passage in a fluid channel from the inlet to a measuring section and a fluid channel from the measuring section to the outlet, the measuring section is located in the middle of the fluid channel connecting the inlet and the outlet, so that manipulation from the inlet to the outlet takes place in one direction on the substrate. Even when analyzing a large number of sample droplets, by transport of the droplets substantially in one direction, it is possible to complete measurement in a short time.

摘要： There are provided a chemical analysis apparatus and an analysis device in which predetermined quantities of a sample and a reagent are presicely pipetted, then are subjected to various processes, and are tested by a test device. Thus, the chemical analysis apparatus comprises the analysis device, an oil supply portion, a sample pipetting portion and a reagent pipetting portion. The analysis device comprises an upper board provided with a common electrode, and a lower board provided with a drive electrode including a train of a plurality of electrodes. Oil is filled in a space defined between the two boards, and liquid drops of the sample, the reagent and the like are formed in the oil. The common electrode is applied thereto with a negative voltage or is grounded while a positive voltage is applied to electrodes on the drive electrode side in order to decrease a contact angle in a zone where the voltage are applied to the electrodes, and accordingly, the wettability is enhanced, thereby it is possible to displace the liquid drops.
