Description
Ntot1 TC (LR) total nitrogen powder test enables photometric determination of total nitrogen in the measuring range 0,5–25,0 mg/l Nges. The kit supplies reagents for 50 tests, uses a 2 ml sample volume and is compatible with both 16 mm and 28 mm round cuvettes. Digestion is performed at 120 °C for 0,5 h by the persulfate method and the procedure corresponds to ISO 23697-1, DIN EN ISO 11905-1 and DIN 38405-9. Fully usable with PhotoLab® and pHotoFlex® photometers, this powder test from manufacturer WTW - a Xylem brand is intended for water and wastewater laboratories requiring standardised total-nitrogen analysis. Combicheck CC50 supports quality control and batch certificates are available on request. The combination of defined digestion conditions and instrument-matched chemistry delivers consistent total-nitrogen results for environmental monitoring and process-control applications.

Questions about Ntot1 TC (LR), Total Nitrogen Powder pillow Measuring rang
What is this article?
Ntot1 TC (LR), Total Nitrogen Powder pillow Measuring rang is the article on this page. Luminix Health distributes WTW - a Xylem brand for laboratory use. It sits in ICP, AAS & ion standards, inside Analytical standards & reference materials, in Lab chemicals.
An ICP, AAS or ion standard is a solution of a stated element or ion at a stated concentration, with an uncertainty. It is the calibration point of a spectrometer or an electrode. The matrix, often dilute acid, has to match the method. A standard past its expiry is not that concentration.
A reference material is the article against which another result is compared. Its value is stated, and the uncertainty of that value is part of the product. An ICP or ion standard is a solution of known concentration. A volumetric standard is for titration. A chromatography standard is the peak you match. The grade names, including pharmacopoeia and ASTM, say which impurities were limited. Identity is checked on PubChem. Names follow IUPAC. Medicinal grades follow the European Pharmacopoeia and USP.
Which category should I open next?
