    摘要: A pH electrode arrangement comprises an inner wire electrode of silver sulfide, and a fill solution comprising a solution of sodium thiosulphate, a buffer, and an antioxidant. The arrangement has a fast response to a change in temperature, a half cell near .+-.500 mV, and an isopotential point near 7 pH.

    摘要: The device (1) has a cell (3) with an electrode structure for carrying out electrochemical detection or measurement of a liquid sample. A means for mechanically or pneumatically drawing the liquid sample into the cavity (20) of the cell (3) is provided. The drawing means may be in the form of a strip (10) which is mechanically drawn through the cell (3) drawing the liquid sample into the cavity (20) of the cell (3). The strip (10) can have a V-shape (44) portion which is placed in the liquid sample before the strip (10) is drawn through the cell (3).
