摘要： PROBLEM TO BE SOLVED: To stabilize a chlorine ion selective electrode made of a thiourea type compound for a long term by fixing neutral carrier type ligand associating with chlorine ion by hydrogen bonding to the macromolecular skeleton of an ion-sensitive film. SOLUTION: The ion-sensitive film 4 is stuck to the end part of a cylinder 1 receiving inner liquid 2 and an inner electrode 3 in the electrode cylinder 1. This electrode 3 is soaked in a sample solution together with a reference electrode made of a calomel electrode or the like, and potential difference of electromotive force of the chlorine ion selecting electrode is measured by an ordinary method based on the reference electrode. A macromolecule fixing film type ion-sensitive film containing macromolecule fixing ligand is used. For the manufacturing method of the sensitive film 4, an ion film fixing neutral carrier type compound meeting with chlorine ion by hydrogen bonding to a macromolecular skeleton as ligand is used. Consequently, even when an obstacle substance coexists in a measured liquid, the chlorine ion can be selectively detected without being influenced by it, and selective ability of response against the chlorine ion is high for a long term and measurement of high accuracy becomes possible.

摘要： PROBLEM TO BE SOLVED: To provide a reliable ion selective electrode that has superior breakdown voltage characteristics and can be stably used for a long time. SOLUTION: In an ion selective electrode using an ion selective sensitive film 4 containing an ion exchange polymer, a buffer member 5 is arranged between the ion selective sensitive film 4 and an electrode body 1. Preferably, a macromolecular elastic body, especially, synthetic rubber, is contained in the buffer member 5. It is ideal to use one of chloroprene rubber, nitrile rubber, and styrene-butadiene rubber as the synthetic rubber, thus absorbing external pressure fluctuation and internal stress by the buffer member and hence obtaining the electrode with high mechanical strength.

摘要： PROBLEM TO BE SOLVED: To enable the improvement of selectivity to bivalent ions by impregnating an ion exchange resin film with lipophilic compounds and forming polymers on its surface. SOLUTION: Alkane, ester, ether, etc., are used as lipophilic compounds, which are neutral. An ion exchange resin film 4 is glued to the end part of a cylindrical polyvinyl chloride sensor main body 1, and the sensor main body 1 is filled with an internal solution. An internal solid electrode 3 formed of silver/silver halide is immersed in the internal solution, one end of a lead wire 5 for deriving signals is connected to the metal part of the internal solid electrode 3, and the other end is connected to an external measuring circuit. Each approximately 2 mM of 1-octene, styrene, and divinylbenzene are dissolved in approximately 20 ml of methanol, and in this solution the ion exchange resin film 4 is immersed for approximately 1 hour and heated at approximately 60 deg.C for approximately 2 hours. By this, it is possible to obtain a selectivity- improved highly reliable sensor.

摘要： PROBLEM TO BE SOLVED: To improve the stability of electromotive force of an ion sensor by using a cation in which an ion sensitive film or an inner electrode shows response as the cation of internal electrolyte, and using an anion in which the inner electrode does not show response as the anion of the internal electrolyte. SOLUTION: An electrode body 1 has an internal electrolyte 2 built-in itself, and is provided with an inner electrode 3 coming into contact with the internal electrolyte 2, and a sensitive film 4 coming into contact with the internal electrolyte 2 is bonded to the end of the body 1. A cation (potassium ion) in which the ion sensitive film 4 shows response and a cation (silver ion) in which the inner electrode 3 shows response are mutually mixed to be used as the cation of the internal electrolyte 2, and an anion (nitric ion) in which the inner electrode 3 does not show the response is used as the anion. In the above style, the electromotive force of an ion sensor is not influenced by the concentration of the internal electrolyte 2. If the concentration fluctuates according to the condition of using and keeping, the electromotive force is stable, and a drift does not occur.

摘要： PURPOSE: To provide a practical ion sensor which can be sufficiently applied to a flow type sensor, etc., and has a small size, and high stability by reducing the thickness of an insulated gas field effect transistor layer. CONSTITUTION: In an ISFET having an ion sensitive film 4, an insulated gas field effect transistor and a support 2, the transistor layer is reduced in thickness, and hence a sensor structure in contact with a protrusion can be formed at a sample channel. Accordingly, the ion sensor in which the electrode performance can be maintained for a long period can be obtained without the problem of carry-over based on the delay of the junction between the film 4 of the sample in the channel and a substrate. Since the accuracy of the characteristics of the ion sensor is improved, it can be used for a long period, and high reliability is obtained.

A part of light waves is transmitted through a living body 7, it is absorbed by a component, to be measured, in blood 9 which flows inside a blood vessel 8, and an optoacoustic radiation is induced. Optoacoustic waves which have been radiated are converted into an electric signal by an acoustic detector 10 inside the cell 6, the electric signal is amplified and waveform-shaped 11, the signal is inputted to a frequency difference detector 12, and the signal is detected and quantified by a frequency analyzer 15 and a central control unit 16.

摘要： PURPOSE:To exchange data between plural and different application programs at low cost by generating original code data from segmented area data and inputting it to a different application program waiting for input. CONSTITUTION:The diagram group information storage part 10 of a computer device stores diagram group information on respective application output screens. Then, the designation of an area from which data is segmented is received in one application output screen 1 (step 100). Then, the diagram group information storage part 10 is referred to based on the designated area and code data shown in the designated area is obtained (step 101). At last, obtained code data is inputted to a different application output screen 2 waiting for input (step 102). Thus, data can be exchanged between plural application programs at low cost without being conscious of a protocol which a communication control program supplies.
