Miniature probe having multifunctional electrodes for sensing ions and gases

摘要: A miniature probe for simultaneously sensing ion concentrations and partial pressures of gases in a sample comprises plural electrode systems at least one which is surrounded by an electrolyte gas permeable or diffusion barrier. The are united structurally to form probe. Various potentials measured between components the indicative inserted. Potentials certain internal electrodes external other ions gases. Partial oxygen carbon dioxide hydrogen, bicarbonate cations anions typical constituents that can be determined with
