Merck 114763 Nitrogen (total) Cell Test Method: photometric, DMP 10 - 150 mg/l N
Catalogue Number
114763
Overview
The method is analogous to DIN 38405-9.
The digestion is analogous to EN ISO 11905-1.
This Spectroquant® Nitrogen (total) Cell Test allows the reliable determination of total nitrogen in water samples. Total nitrogen is the sum of total Kjeldahl nitrogen (organic nitrogen and ammonia), nitrate, and nitrite. Prior to the determination the sample needs to be digested in order to transfer organic and inorganic nitrogen containing compounds into nitrate that further reacts to a photometrically analyzable compound.
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.
