Verfahren zur Bestimmung einer Gaskonzentration

An embodiment of a sensing element (10) for a gas vapor detector (24) is formed from a gold-palladium alloy. The sensing element (10) is highly sensitive to phosphine or arsine gas. The by volume palladium concentration of the sensing element is typically less than 20 %. The sensing element (10) is...

Zusammenfassung:	An embodiment of a sensing element (10) for a gas vapor detector (24) is formed from a gold-palladium alloy. The sensing element (10) is highly sensitive to phosphine or arsine gas. The by volume palladium concentration of the sensing element is typically less than 20 %. The sensing element (10) is used as an active element in a gas vapor detector (24).
