| 摘要 |
Methods for detection of acetylene, acetylene concentration and changes in acetylene concentration in a mixture of gases are provided. The gas mixture includes acetylene and hydrogen and may be a hydrogen gas stream or a gas stream also including ethylene. The methods of the invention can also detect acetylene in a gas mixture dissolved in a liquid. The methods of the invention rely on the use of metal-insulator-semiconductor (MIS) sensors in which the metal layer is a continuous layer of a binary alloy selected to facilitate acetylene detection such as alloys of palladium with a second metal such as silver, gold or copper.
