The User Guide/Instructions for Use (IFU) for Product 1.14739 states explicitly that "this test is not suited for seawater". This is likely due to the presence of interfering substances such as Magnesium ions (Mg2+) in the seawater. Consider Product 1.14657, which is a somewhat less sensitive colorimetric assay called Ammonium Test in freshwater and seawater.

General description
Method: Photometric, 0.010 - 2.000 mg/L (NH4-N), 0.01 - 2.58 mg/L (NH4+), Spectroquant®
The method corresponds to ISO 23695, a norm standardizing the use of this "small-scale sealed tube method" for this important parameter. The method is also analogous to EPA 350.1, APHA 4500-NH3 F, ISO 7150-1, and DIN 38406-5.
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 Test Kits are equipped with the unique Live ID (2D barcode) which allows seamless method recognition and contains essential information such as lot number, expiry date, and automatic calibration updates.
