title: Halothane interference at an amperometric oxygen electrode: the development of an oxygen/halothane sensor.
abstract: The role of electrode materials in the reduction of halothane and oxygen mixtures at rotating and stationary electrodes is considered. Halothane is found to be electroactive within the available electrode-potential range on silver and on gold. Double potential step experiments are considered in order to isolate the individual halothane and oxygen signals. A double integration, single potential step technique is evaluated for the quantitative simultaneous measurements of oxygen and halothane on gold. The influence of electrode purity is discussed in terms of a reaction mechanism and electrode output error.
