摘要： A calibration solution, which is used when measuring the ion concentration of solution under examination such as blood or other body fluids using a pH sensor or the like ion sensor with a solid electrode, is prepared by adding NaCl to a standard buffer solution and thus setting the ionic strength of the solution to be substantially identical with the ionic strength of solution under examination. A sensor calibration method is also disclosed, in which at least two reference calibration solutions having different pH values are prepared, the electromotive force of the sensor in these calibration solutions is measured by immersing the sensor in the solutions, and a calibration formula is produced from the electromotive force for the pH values of the reference calibration solutions. A predetermined amount of bicarbonate buffer solution is added to the calibration solution to maintain a substantially constant ionic strength of the solution, thus permitting simultaneous calibration of an ion sensor and a gas sensor.

摘要： An electrochemical cell is formed by immersing an electrochemical ion sensor and a reference electrode into a solution of interest, the electrochemical ion sensor exhibiting ion selectivity with respect to an ion of interest and having a high electrode resistance. A current which flows through the electrochemical cell is measured while the potential of the electrochemical ion sensor is held to a constant potential with respect to the reference electrode.

摘要： A biological information measurement apparatus is adapted to measure biological information in an extracorporeal circuration or in a living body by various measurement circuits comprising circuit elements which are not affected by electrical disturbances, and to transmit the results of measurement in the form of a non-electrical signal which is not affected by electrical disturbances. Measured values from measurement sections are gathered at a central processing section separated from the measurement sections. The processing section converts the measured values into output values, compensates the values for temperature and outputs the values to a display unit and recorder.
