Nitrogen analysis plays a crucial role in water quality monitoring for surface water, drinking water, wastewater, and groundwater. The MACHEREY-NAGEL NANOCOLOR® Total Nitrogen Tube Test offers a simplified, accurate, and time-saving solution for photometric determination of total nitrogen. Designed for compatibility with MACHEREY-NAGEL photometers, this test ensures reliable results while eliminating unnecessary steps in the testing process.
How Does the NANOCOLOR® Total Nitrogen Test Work?
The test utilizes oxidative decomposition, followed by photometric analysis using 2,6-dimethylphenol in a sulfuric/phosphoric acid mixture. This method ensures all organic and inorganic nitrogen compounds are oxidized to nitrate, which reacts with 2,6-dimethylphenol to form a measurable compound.
Highlights of the Test Process:
Simplified Procedure: Predosed decomposition reagent in the tubes eliminates the need for manual reagent addition.
Enhanced Precision: The NANOFIX capsule compensates for interferences, ensuring reliable readings.
Time-Saving: Fewer steps mean faster workflows, allowing users to complete analysis more efficiently.
