Analyzers of total nitrogen and carbon "TOPAZ"
Analyzers of total nitrogen and carbon "TOPAZ" are designed to determine the elemental composition of samples of drinking water, water, packaged in containers, as well as various types of natural, waste and process waters.
Analyzers of total nitrogen and carbon "TOPAZ" can be used in analytical laboratories of enterprises of various industries, laboratories of scientific research institutes, as well as for carrying out sanitary and environmental control of various types of waters.
The TOPAZ C modification is designed to measure the mass concentration of total carbon (in the composition of organic carbon, as well as all forms of inorganic carbon, including carbonates, bicarbonates, cyanides, cyanates, thiocyanates, carbon monoxide and dioxide and elemental carbon).
"TOPAZ NC " modification is designed for simultaneous measurement of mass concentrations of total nitrogen and total carbon.
The principle of operation of the TOPAZ analyzers is based on high - temperature thermocatalytic oxidation of nitrogen and / or carbon compounds contained in a water sample, followed by the detection of oxides of elements and the calculation of the initial content in the sample of all forms of nitrogen and / or carbon compounds.
In the TOPAZ N modification, the determination of total nitrogen is made according to the measurement of the concentration of nitrogen oxide using chemiluminescence detection, ie, by measuring the intensity of chemiluminescence that occurs in the gas mixture during the reaction of nitrogen oxides with ozone (the ISO 11905 - 2 method is implemented).
In the "TOPAZ S" modification, the determination of total carbon is carried out according to the measurement of the concentration of carbon dioxide using an infrared detector. In accordance with GOST R 52991 - 2008 (ISO 8245: 1999), a separate determination of the total carbon content and the total inorganic carbon is performed, followed by the calculation of the total organic carbon content by the difference between the total carbon content and the inorganic carbon content, or direct determination of the total organic carbon
Both of the above methods are implemented in the TOPAZ NC modification: ISO 11905 - 2 and GOST R 52991 - 2008 (ISO 8245: 1999), thus, the modification of the TOPAZ NC analyzer allows measuring the total nitrogen content in the water sample, as well as the total and inorganic carbon.
