摘要： PROBLEM TO BE SOLVED: To avoid mixture of heavy metal elements into a silver halide layer and correctly determine the activity of specific ions in a sample by using an oxidizing agent which does not influence silver halide generated. SOLUTION: A silver halide layer is formed by oxidizing a surface of a silver layer with a peroxide in the presence of a halide. At this time, if the used peroxide is, for example, hydrogen peroxide, the silver layer can be uniformly oxidized because the hydrogen peroxide foams severely during the reaction. Moreover, heavy metal elements originated from the oxidizing agent are prevented from being included in the silver halide because the hydrogen peroxide is dissolved to oxygen and water. The ion-selective electrode with an ion selectivity applied to the silver/halide silver reference electrode shows superior electrical responsivity.

摘要： PURPOSE: To prevent the deterioration of the performance of an element by positively discharging gas or the like generated by this processing when heat fusing is performed at the specified part of a dry analyzer element and sealing is performed. CONSTITUTION: The lower surface of a surrounding means 12 is opened. Gas outside the surrounding means 12 flows into the surrounding means 12 through this opening due to the gas sucking operation by a gas intake part. At the same time, the gas or the like generated from heat fused part 16 of a web 10 is sucked into the surrounding means 12 together with the inflow gas. The gas or the like sucked into the surrounding means 12 is lifted up between the outer wall of the tip part of a laser torch 11 and the inner wall of the surrounding means 12 and sucked into the direction of the sucking part through an exhaust tube part 13 and a duct 14. A part of the gas is removed by a filter and the like. Furthermore, the web part other than the heat fused part 16 of the web 10 of a dry analysis film is coated with a light screening mask 15.

摘要： PURPOSE:To allow the calibration of measured values with good accuracy by estimating the measured values at the virtual point on the outside of the upper limit and lower limit of the display values of calibration liquids in addition to the measured values of the calibration liquid having prescribed representation values and determining the calibration curve including these virtual measured values. CONSTITUTION:The measured values h, m, l are determined and plotted with the three calibration liquids having the prescribed standard representation values H, M, L by the same method as the method for executing the quantitative analysis of the components to be examined. The virtual measured value corresponding to the representation value Hmax of the upper limit of the determination is designated as hmax and the virtual measured value at the 0 point (representation value=0) as C0. The virtual measured value hmax and C0 at this virtual point are determined. The calibration curve is usually a quadratic function in many cases and, therefore, linear equation is obtd, from the three points (l, L), (m, M), (h, H) and (hmax, Hmax) is determined from the point intersecting with Y-Hmax and (C0, 0) from the point intersecting with the X axis. The calibration curve is obtd. by using the five points (C0, 0), (l, L), (m, M), (h, H), (hmax4X, Hmax).

摘要： PURPOSE:To prevent the evaporation of a solvent and the use of the liquid concentrated to an undesirable extent, by providing a container with the members floating on the liquid surface and occupying at least one-half of the liquid surface and with the spherical members of not less than four having a greater specific gravity than that of the liquid and placed therein to a predeter mined height from the inner surface of the container bottom. CONSTITUTION:It is desirable that a clearance between a floating member and the inner surface of wall of a container in the liquid storage portion be made as small as possible. And it is important that the material of the floating member do not affect the liquid composition. By forming a hole in the middle of this floating member, the liquid can be removed by a pipette or the like through the hole, without forcing the floating member into the liquid. The material of the spherical member is greater in specific gravity than the liquid and it is important that this material be the type which does not affect the liquid composition. These spherical members are placed in the container to a depth corresponding to that of the liquid in the minimum limit of the amount, with changes in the liquid concentration resulting from evaporation confined within a practically negligible limit.

摘要： PURPOSE:To improve the accuracy of calibration curve formation by incorporating a water-insoluble dispersion phase into a calibration liquid for forming the calibration curve of an analysis system. CONSTITUTION:The water-insoluble dispersion phase is incorporated into the calibration liquid for liquid component analysis to determine the specific component in whole blood. A dry type analysis material contg. at least one reagent in a water permeable layer and having a porous development layer on the outermost layer is used and the liquid contg. the water-insoluble dispersion phase is used as the calibration liquid at the time of a quantitative analysis of the specific analyte in the whole blood. The water-insoluble dispersion phase is selected from the group consisting of a styrene polymer, copolymer of styrene and monomer copolymerizable therewith, etc., if said phase is a solid phase. The water-insoluble dispersion phase is selected from the group consisting of adipate, sebacate, etc., if said phase is a liquid phase. The water-insoluble dispersion phase is an emulsion or suspension which has grain sizes ranging 0.01-10mum and can be uniformly mixed with an aq. phase by a simple stirring operation. Said phase may not always be a liquid dispersion.
