A method and apparatus for analyzing fluid by a multi-fluid modulation mode is characterized by subjecting a plurality of sample fluids (which may be different or a single sample fluid divided into a plurality of systems) to a fluid modulation by reference fluids at various frequencies, respectively. An analytical portion provided with only one sensor is simultaneously and continuously supplied with the respective sample fluids. An output signal from the sensor in the analytical portion is divided into signal components of the respective modulation frequencies for the respective sample fluids to rectify and level, whereby obtaining analyzed values about the respective sample fluids is achieved.

Method for analyzing fluid by multi-fluid modulation mode

A reference electrode for use in testing liquid at a high pressure, has an internal liquid containing body having an internal liquid containing space therein and a liquid-junction one side of which is exposed to the high pressure liquid to be tested and the other side of which is exposed to the internal liquid contained in the internal liquid containing space. A reference electrode body surrounds the internal liquid containing body and defines a pressure compensating space between the internal liquid containing body and the inside of the reference electrode body, the pressure compensating space being open outwardly of the reference electrode body at a part there of which is exposed to the high pressure liquid to be tested when the reference electrode is in position for normal use, the pressure compensating space receiving the high pressure liquid to be tested therein. A flexible bellows is provided between the spaces and in liquid tight engagement with the internal liquid containing body for compensating for the pressure of the high pressure liquid to be tested on the internal liquid through the liquid-junction.
