Abstract
In systems for rapid sequential analysis of fluid samples, such as blood samples, an electrochemical sensor is capable of equally rapid, sequential sample response by avoiding the need for equilibration during the measuring phase, and by substantially replacing the electrolyte acceptor for each sample. The sensor is made up of a pair of electrodes, an electrolyte acceptor, and a gas permeable membrane separating the electrolyte from the sample stream. Samples are passed rapidly by the membrane, and at the end of each such pass, the electrodes are polarized for a certain period, the flow of electrical current is measured, and the electrolyte is flushed and replaced by new electrolyte. This membrane material can be hydrophobic and also hydrophilic in nature.
