ORGANIC ELEMENTAL ANALYZER (CHNS/O)

ORGANIC ELEMENTAL ANALYZER (CHNS/O)

The elemental analyzer is a device used for quantitative determination in organic samples containing carbon, hydrogen, nitrogen, sulfur and oxygen as the basic elements of nature. The basic operating principle of the device is based on the burning of the sample at high temperature (≥1100º C). The gaseous sample is sent to the chromatography column with an inert gas (helium, He) used as the carrier. Here, the gaseous sample is combusted with oxygen (O2) gas and passed through the oxidation zone followed by oxidation with suitable catalysts to fully perform the quantitative combustion process. After the process, C, H, N, S elements are converted to CO2, H2O, N2 and SO2 gases and sent to the thermal conductivity detector to record the electrical signal proportional to the amount of each gas. This electrical signal then gives, for example, the percentage of elemental composition in proportion to the curve areas obtained in the spectrum. In the determination of the oxygen element, the sample is pyrolyzed by hydrogen-helium (H2-He) gas mixture. All oxygen-containing products formed as a result of combustion are converted to carbon monoxide by the catalyst system and similarly elemental determination is made.

 

With the elemental analysis device within the body of ARUM, the determination of CHNS elements from samples can be done in one time and in a short time such as 8 minutes. In the system, the oxygen analysis can be readily carried out consecutively and the quantitative determination of the five elements (CHNS / O) can be completed quickly. With the elemental analyzer, a wide range of solid or liquid organic or inorganic samples such as industry, environment, geology, food fields can be examined, especially in the chemical and pharmaceutical sectors. Empirical molecular formulas can be determined by analysis of organic substances.
