摘要： PROBLEM TO BE SOLVED: To provide a compact automatic analysis apparatus. SOLUTION: A mirror 27 is installed behind a photometry cell 4 for accommodating each kind of solution to be analyzed, thus enabling luminous flux 30 for measurement to pass a reaction liquid 40 for two times and at the same time enabling the luminous flux to pass a step section 4A that is formed at the upper section of the photometry cell. As a result, the thickness of the photometry cell 4 can be thinned for making compact the apparatus. At the same time, a passage length of fixed luminous flux can be always maintained without being affected by the difference of the amount of the reaction liquid and the chattering of a liquid surface, thus achieving an accurate analysis.

摘要： PROBLEM TO BE SOLVED: To obtain a sample separating apparatus in which flows of a sample liquid are made uniform in a gap inside a chromatographic column, in which separated components are not mixed again and whose separating capability is high, by branching the sample liquid into a plurality of flow passages for separation, which are formed on a flat board and whose cross-sectional shape and length are equal. SOLUTION: A sample liquid of a set amount is put on the flow of a carrier liquid, and it is introduced into the inside from the entrance of a sample separating apparatus. At this time, since both the cross-sectional shape and the length of respective separating flow passages are equal, pressure drags in flow passages which are continued to respective separating flow passages 451, 461 are equal. Consequently, the carrier liquid which contains the sample liquid is branched equally into the flow passages 451, 461 at an equal flow rate so as to flow. In this manner, the flow of the sample liquid which approaches the branch part 452 of the flow passage 451 is branched into flow passages 453, 454, which are continued to it, at an equal flow rate so as to flow because a flow passage resistance is equal. In the same manner, the sample liquid is branched at an equal flow rate even in the flow passage 461 through a branch part 462 to flow passages 463, 464. Components which are separated in the respective flow passages are joined without being mixed with each other, and they go out from an exit 43 to be sent to a flow cell.

摘要： PROBLEM TO BE SOLVED: To provide a micro pump having a high rendering property by providing a fixed electrode and a movable electrode as a driving device for diaphragm of a liquid feeding chamber on one side of a diaphragm, and driving a pressurizing pin provided in the movable electrode at the predetermined speed. SOLUTION: At the time of feeding liquid, voltage is applied between a fixed electrode 11 and a movable electrode 12 so as to attract the movable electrode 12 to the fixed electrode 11, and a pressurizing pin 13 bonded to the movable electrode 12 thereby pushes a liquid feeding diaphragm 9 in the direction of reducing volume of a liquid feeding chamber 6, and a flow passage is opened by an outlet fluid resistor element 8 provided on the way of an outlet flow passage 4, and the fluid is discharged from a discharge nozzle 14. On the other hand, when the voltage applied between the fixed electrode 11 and the movable electrode 12 is shut off, the liquid feeding diaphragm 9 is moved in the direction of increasing the volume of the liquid feeding chamber 6, and the flow passage is closed by the outlet fluid resistor element 8, and an inlet flow passage 3 sealed by an inlet fluid resistor element 7 is opened so that the fluid flows into the liquid feeding chamber 6 through a fluid lead-in port 2. This operation is repeated so as to continuously feed the liquid.
