Ammonium Cell Test (catalogue 114559) is a photometric reagent kit designed for the determination of ammonium in aqueous samples. It measures ammonium nitrogen in the range of 4.0–80.0 mg/L (NH₄-N) equivalent to 5.2–103.0 mg/L (NH₄⁺) and is compatible with Spectroquant® photometers. The test enables fast, cyanide-free ammonium analysis for environmental, food & beverage and industrial water quality applications.
The Ammonium Cell Test (catalogue No. 114559) from the Spectroquant line by Merck is a ready-to-use photometric reagent test for the quantification of ammonium in aqueous samples. The method is based on the indophenol blue reaction and provides results in the range of 4.0–80.0 mg/L ammonium nitrogen (NH₄-N) which corresponds to 5.2–103.0 mg/L total ammonium (NH₄⁺). The test is compatible with Spectroquant® photometers and suitable for rapid analysis of ammonium in wastewater, surface water, groundwater, seawater, food & beverage and other environmental samples.
