title: Sweep potential polarography and multiwire surface tissue electrodes.
abstract: A multitipped seven barrelled platinum electrode for brain surface oxygen measurements during neurosurgery is described. Its performance has been examined when employed under conditions of sweep potential polarography. Although there is no plateau within the oxygen polarogram, the electrode displays linear performance within the physiological range, gives reproducible results in practice, has an acceptable temperature coefficient and a fast response time.
