Integriertes mehrschichtiges analytisches Element.

摘要

A multi-layer analysis element including an endogenous ammonia trapping layer, an ammonia producing layer containing a composition capable of reacting with an ammonia producing substance to produce gaseous ammonia, and at least one layer essentially incapable of trapping ammonia and essentially incapable of producing ammonia, and capable of preventing the diffusion of ammonia, disposed between the endogenous ammonia trapping layer and the ammonia producing layer. The unified multi-layer analysis element according to the invention is useful for the quantitative analysis of ammonia producing substances in aqueous biological food samples, with a high degree of sensitivity and accuracy, using a simple procedure.
