Abstract:
Classical analysis of water samples for nitrogen content is laborious, time consuming and generates hazardous waste. Total Kjeldahl Nitrogen (TKN) measurement does not take into account the contributions of nitrites and nitrates, nor variability in recovery as a result of different salt content of the samples. The current EPA definition for total bound nitrogen (also called bound nitrogen or TNb) is TKN plus nitrite and nitrate nitrogen. Recently published analytical methods now provide for instrumental analysis of TNb which saves time, minimizes waste, increases accuracy, and reduces variability. The Shimadzu bench top TOC-L with TNM-L and the on-line TOC-4200 with TNM can be used to determine total nitrogen (TNb) as well as simultaneous TC or NPOC analysis.
