Description
NH4-1 TP ammonium / ammonia powder test is a photometric reagent kit for the determination of ammonium and ammonia, covering 0,01–0,50 mg/l NH4-N and 0,002–0,092 mg/l NH3. The kit is designed for a 10 ml sample volume and supplies reagents for 100 tests using 20 mm cuvettes. Analysis follows the salicylate method and corresponds to DIN 38406-E5-1 and ISO 7150-1. The powder reagents work with PhotoLab® and pHotoFlex® photometers, supporting routine photometric evaluation in water-quality and environmental laboratories. Available from manufacturer WTW - a Xylem brand, the NH4-1 TP format offers practical powder dosing that streamlines sample preparation and helps maintain consistent results for low-level ammonium and ammonia monitoring. Typical use includes wastewater control, surface-water assessment and laboratory process checks where nitrogen species must be quantified reliably. Batch certificates can be requested for quality documentation. This powder test provides a compact, standards-aligned solution for sensitive photometric ammonium and ammonia determination.
This article is part of ICP, AAS & ion standards, in Analytical standards & reference materials.

Questions about NH4-1 TP, Ammonium / Ammonia Powder pillow Measuring range
What is this article?
NH4-1 TP, Ammonium / Ammonia Powder pillow Measuring range 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?
The category is Analytical standards & reference materials. The sub-category is ICP, AAS & ion standards. The catalogue is Lab chemicals.
Shelves beside this one are Chromatography standards (GC, HPLC, pesticides), Reference substances & reagents (other), Volumetric standard solutions (titration), Reagents for analysis (Ph. Eur., ASTM, DIN), Spectroscopy & physical property standards and Indicators & indicator solutions.
What should I check before I order?
When this page shows a safety data sheet, use that manufacturer file. Hazard text does not belong in the sales description. For a pack size, a grade or a certificate that is not on the page, send a quote request or contact the team.
