General description

Method: Photometric, 0.5 - 16.0 mg/L (NH4-N), 0.6 - 20.6 mg/L (NH4+), Spectroquant®

The method is analogous to EPA 350.1, APHA 4500-NH3 F, ISO 7150-1, and DIN 38406-5.

USEPA approved for drinking water and wastewater.

The Spectroquant® Ammonium Cell Test allows the cyanide-free quantification of ammonium in wastewater, groundwater, surface water, and seawater. Typically, ammonium enters water sources as runoff from fertilized agricultural areas and enhanced levels are important indicators for faecal pollution.

Further fields of applications are the analysis of foods & beverages and of environmental and agricultural samples (e.g. soil).

The Spectroquant® Cell Tests come with prefilled 16 mm round cells and all the required reagents to perform the analysis according to the instruction leaflet provided.

All Spectroquant® Cell and Reagent Tests are equipped with the unique Live ID which allows seamless method recognition and contains essential information such as lot number, expiry date, and automatic calibration updates.
