Photometric Analysis with Spectroquant® Instruments & Test Kits

General Description

Method: photometric 0.5 - 15.0 mg/l N Spectroquant^®
The digestion is analogous to DIN 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 and reduced nitrogen, 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 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.

Application

• Study on water quality and genotoxicity of surface microlayer and subsurface water in Guangzhou section of Pearl River:This study investigates the water quality in the Pearl River, focusing on nitrogen content analysis and its implications for environmental safety and water management (Yu et al., 2011).


• Scaling leaf respiration with nitrogen and phosphorus in tropical forests across two continents:Focuses on the ecological aspect of nitrogen cycling, particularly how leaf respiration is scaled with nitrogen content in different forest ecosystems (Rowland et al., 2017).
