Description
NANOCOLOR Total Nitrogen TNb 22 is a round cuvette test for photometric determination of total bound nitrogen (TNb) in aqueous samples over a measuring range of 0,5–22,0 mg/L N. It supports environmental, wastewater and process laboratories that track nitrogen loads for treatment control and effluent assessment. Each pack provides 20 determinations and is supplied as a double box (box A and box B) in a cardboard sleeve, keeping digestion and detection reagents organised for sequential use. The round-cuvette format is intended for standard NANOCOLOR photometric evaluation and helps streamline multi-step total-nitrogen workflows. Offered by manufacturer Macherey-Nagel, the kit is aimed at routine laboratory practice where reproducible TNb data within the stated range are required. Transport classification is UN 3316 chemical test kit, class 9, packing group II, with limited-quantity provisions as indicated. This total-nitrogen test complements phosphate, oxygen and related NANOCOLOR parameter sets used in comprehensive water-analysis programmes.

Questions about NANO total Nitrogen TNb 22
What is this article?
NANO total Nitrogen TNb 22 is the article on this page. Luminix Health distributes Macherey-Nagel for laboratory use. It sits in Cuvette tests (Nanocolor), inside Test kits & water analysis, in Lab chemicals.
A cuvette test is a ready optical cell containing the reagents for one water or one chemical determination. The sample is added, the cell goes into a photometer, and the range printed on the box is the range of the answer. It is a method, packaged, not a bottle of reagent to assemble.
A test kit turns a chemical question into a colour, a titre or a reading on a strip, so the operator does not have to assemble the method from separate reagents. A cuvette test is a ready optical cell. A strip is a field reading. The range printed on the kit is the range where the answer means something. Outside it, the kit is silent or wrong. The substances inside are on PubChem. Water measurement traces to NIST.
