PROCESS AND DIAGNOSTIC DEVICE FOR THE DETERMINATION OF AMMONIA AND OF SUBSTRATES WHICH REACT WITH THE FORMATION OF AMMONIA

摘要

The present invention provides a diagnostic device for the determination of ammonia and of substrates reacting with the formation of ammonia, comprising a handle, an indicator layer for gaseous ammonia fixed thereon and an alkaline buffer containing reaction layer which optionally contains additional reagents reacting with the substrate with the formation of ammonia, wherein the indicator layer is securely attached to the handle and above it is arranged the reaction layer at a distance of 10 to 200.mu. by means of a distance piece, the distance piece and the reaction layer being easily removable from the indicator layer; there is also provided a method of detecting ammonia and substrates reacting with the formation of ammonia, using the above diagnostic device.
