摘要： An automatic analysis apparatus with a liquid level detection function includes a pipetting device for pipetting a liquid sample from a sample cup to a reaction container by using a pipetting probe that serves as a first capacitor electrode. A sample cup holding means serves as a second capacitor electrode having a ground potential. The conductor material is arranged along a direction in which the pipetting probe moves down for pipetting and is separate from the pipetting device. The conductor material has the same ground potential as that of the sample cup holding means and also serves as a second electrode whereby at any one time either of the sample cup holding means and the conductive material serves as a second capacitor electrode in combination with the first capacitor electrode. An a electrical detector is provided for detecting a change of electrode static capacitance between the pipetting probe and the sample cup holding means and between the pipetting probe and the conductive material as of level detection of the liquid sample. Measurement means are also provided for measuring an ingredient of the reaction container.

摘要： An automatic analyzer according to the present invention is compact, mounting great number of reagents, having high processing ability. Reagent disks are arranged at inside and outside of a reaction disk. A reagent probe can inject a reagent into the position which is common position of both reagent disks. One of plural reagent probes approaches to one of reagent disks at one cycle. Plural reagent probes alternatively approach to the reagent disk. Therefore, the first reagents and the second reagents can be placed on both reagent disks. The mounting number of reagents can be increased without enlarging an analyzer. The cycle time can be shortened to make an automatic analyzer to have high processing ability.

摘要： An automatic analysis apparatus, in which analysis results of immunoassay analysis items are not influenced by carry-overs between samples even when the same sample container is conveyed both to a biochemical analysis unit and an immunoassay analysis unit to permit sample dispensing. The immunoassay and biochemical analysis units are arranged along a rack conveyor. A carry-over avoidance level is set on a screen every analysis item before start of an analyzing operation. When a sample given an instruction to analyze only analysis items having low carry-over avoidance levels is to be dispensed in the biochemical analysis unit, a dispenser nozzle is subjected to ordinary cleaning by water. When a sample given an instruction to analyze analysis items having high carry-over avoidance levels is to be dispensed in the biochemical analysis unit, a dispenser nozzle is cleaned with a detergent solution and water.

摘要： A gas mixing device of a blood gas analyzer has a substrate made of a material such as silicon and a plate having a flat smooth surface, made of a material such as glass. The plate is bonded to the substrate. The substrate has a plurality of fine elongated grooves extending between inlet and outlet ports formed in the plate. Different gases are introduced through the respective inlet ports, and combined with each other in the gas mixing device. The levels of flow resistance in branch grooves are so determined that the different gases are mixed at predetermined mixing ratios for delivery to the outlet ports. Further, the analyzer includes the gas mixing device and a measuring unit equipped with a plurality of gas measuring electrodes. The mixture gas from the gas mixing device is made to bubble through a buffer solution in a reservoir for producing a standard liquid measuring unit that is delivered at predetermined time intervals to the analyzer for calibration.
