摘要：An electrochemical cell is provided with plural identical selective electrodes andat least one chemical reactor for the indirect measurement of clinical-chemical
parameters. The electrodes are ion- selective for the same ionic species or gas-selectivefor the same gaseous species. One of the two electrodes can be used as a measuringelectrode and the other as a reference electrode. In the case of gas- selective
electrodes, the reference electrode can be selective for a different ionic species. A thirdelectrode with just electrical conducting properties can be provided. The chemicalreactor can utilize immobilized enzymes, or immobilized substrates, or ion exchangeresins, and is preferably connected to the measuring electrode only. Two fluidic pathsmay be provided in the electrochemical cell, as well as one input and two outputs, or twoinputs and just one output in sequence. More sophisticated types of apparatus based onthe same principles, can incorporate two or more different chemical reactors, or elsereactors which can be connected to both the measuring and the reference electrodes,the respective functions of which can be exchanged, or the apparatus can employ a
plurality of elementary electrochemical cells.
