What is an Organic Elemental Analyzer for CHNS?
The elemental analyzer for CHNS is a device utilized for the quantitative analysis of the fundamental atomic building blocks of nature which encompasses carbon, hydrogen, nitrogen, sulfur, and oxygen -. Its fundamental operational principle that underlies the process involves subjecting the sample to intense heat (≥1100º C), whereby the resulting gaseous sample is then conveyed into a chromatography column through the use of an inert gas, helium (He), functioning as the carrier gas.
Within this column, the gaseous sample undergoes combustion with oxygen (O2) and then proceeds through an oxidation zone, followed by oxidation facilitated by appropriate catalysts to ensure a thorough quantitative combustion process. The elements carbon (C), hydrogen (H), nitrogen (N), and sulfur (S) are subsequently transformed into carbon dioxide (CO2), water (H2O), nitrogen gas (N2), and sulfur dioxide (SO2), respectively.
The resultant gases are then directed to a thermal conductivity detector, which records an electrical signal that is proportional to the quantity of each gas present and provides information, such as the percentage of elemental composition, as deduced from the areas under the curve in the spectrum.
Wide Range of Applications of Organic Elemental Analyzers for CHNS
The versatility of organic elemental analyzers for CHNS cannot be overstated, with its ability to handle a broad spectrum of sample types, including liquids, solids, and gases, thus marking elemental analyzers for CHNS as indispensable tools in an array of applications, from environmental monitoring and food chemistry to pharmaceutical analysis and the study of petrochemicals.
Regarding the role of elemental analyzers for CHNS within the petroleum sector, a crucial application involves routinely checking for coke buildup on refinery catalysts to ensure optimal timing for regeneration procedures, which involves controlled carbon burning. As numerous of these catalyst systems contain significant amounts of precious metals like platinum, palladium, and rhenium, mismanaging this testing could result in substantial financial losses. In the realm of food analysis, organic elemental analyzers for CHNS in their determination of nitrogen, which serves as a proxy for protein content, hold immense importance for pricing grains and assessing meat products, and thus, increasingly, combustion analysis is being employed for this purpose.
