VERFAHREN ZUR BESTIMMUNG GASFOERMIGER HYDRIDE.

摘要

A reagent for detecting gaseous hydrides comprises supported on a carrier, e.g. silica, a basic copper carbonate as a component which undergoes color change upon contact with gaseous hydride selected from arsine, phosphine, diborane, hydrogen selenide, germane, monosilane, disilane and dichlorosilane. Upon contact with as low as 0.1 ppm of hydride, the reagent rapidly changes from an initial blue color to a permanent black. The detecting method can be performed also with powder or pellets of the carbonate. …The reagent can be packed in a transparent tube.
