一般描述

Method: photometric, DMP 1.0 - 50.0 mg/l, NO3-N, 4 - 221 mg/l NO3 -Spectroquant®

The method corresponds to ISO 23696-1, a norm standardizing the use of this "small-scale sealed tube method" for this important parameter. The method is also analogous to DIN 38405-9.

This Spectroquant® Nitrate Cell Test allows the accurate quantification of nitrate in water samples. Nitrate is an essential nutrient required for the growth of animals and plants. However, elevated levels of nitrate can be a health risk, in particular for pregnant women and infants. Therefore, nitrate levels in water sources are regulated in many countries.

Further fields of applications are the analysis of foods & beverages (e.g. whey) 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.
