| calomel electrode | An electrode in which the wire is connected through a pool of mercury to a paste of mercurous chloride (Hg2Cl2, calomel) in a potassium chloride solution covered by more potassium chloride solution; commonly used as a reference electrode. (05 Mar 2000) |
| carbon dioxide electrode | A glass electrode in a film of bicarbonate solution covered by a thin plastic membrane permeable to carbon dioxide but impermeable to water and electrolytes; the carbon dioxide pressure of a gas or liquid sample quickly equilibrates through the membrane and is measured in terms of the resulting pH of the bicarbonate solution, as sensed by the glass electrode; commonly used to analyze arterial blood samples.
