The determination of urea and other nitrogen compounds in urine by the DIE method
Authors:P Marik-Korda
Institution:(1) Institute for General and Analytical Chemistry, Technical University Budapest, Hungary
Abstract:The heat of reaction of hypobromite with the non-protein nitrogen compounds contained in urine is very high. This fact can be utilized for the determination of these compounds by the inverse DIE method. The DIE method also allows a separate determination of urea based on the specific action of the enzyme urease.
Zusammenfassung Die Reaktionswärme von Hypobromit mit den im Urin enthaltenen nicht-Protein Stickstoffverbindungen ist sehr hoch. Dieser Umstand kann zur Bestimmung dieser Verbindungen durch die inverse DIE-Methode verwendet werden. Die DIE-Methode gestattet auch die separate Bestimmung von Karbamid aufgrund der spezifischen Wirkung des Enzyms Urease.

By describing the abowe two determinations, we wished to present the applicability of the inexpensive Hungarian instruments for fast and simple determinations in the biochemical field.

This paper completes the material of the Hungarian Symposium on Thermal Analysis.
