Aurora 1030C TNb Module

Aurora 1030C Total Bound Nitrogen (TNb) Analysis Module.

Measuring the total bound nitrogen (TNb) content of water samples provides an indication of the amount of pollutants present in those samples. Total bound nitrogen consists of dissolved ammonia, nitrates, nitrites, amines, and other nitrogen-containing compounds.



The TNb analysis module is an optional accessory for the Aurora 1030C TOC analyzer that allows measurement of total bound (inorganic and organic) nitrogen (excluding N2) concentrations in aqueous samples. Total nitrogen can be measured simultaneously during NPOC and TC analysis or as a separate function when operated in the TNb analysis mode.


Direct measurement of Total Nitrogen (TNb) concentration in aqueous samplesFaster analysis time than Total Kjeldahl Nitrogen (TKN) testing (10–15 minutes versus 2–3 hours)High temperature combustion used in the Aurora TNb is more effective for difficult sample matrices such as brines and particulatesEliminates labor and hazardous chemical exposure associated with TKN digestionTNb module mounts onto the Aurora 1030C TOC Analyzer, requiring no additional lab benchspace
