High-temperature combustion of a sample in the presence of oxygen has been one of the standard methods of elemental analysis for many years, especially for the determination of carbon, hydrogen, nitrogen, and sulphur in organic compounds. In this method, the sample is broken down by the high temperatures, and these elements come out of the sample. In the presence of oxygen, carbon, hydrogen, nitrogen, and sulfur are converted to CO_{2<\/sub>, H2<\/sub>O, NO2,<\/sub> and SO3<\/sub>, respectively. All the combustion and oxidation steps take place inside the CHNS analyzer. Helium is the carrier gas and carries with it the resultant CO2<\/sub>, water, nitrogen oxides, and sulphur trioxides.<\/p>\n}

The amounts of CO_{2<\/sub>, H2<\/sub>O, and SO3<\/sub> are measured by the infrared detection at their respective absorption wavelengths. The NO2<\/sub> content is determined by using thermal conductivity measurement. Before analysis, the device is calibrated with standards with known percentages of carbon, hydrogen, sulphur, and nitrogen to ensure the quantification is accurate.<\/p>\n","protected":false},"excerpt":{"rendered":"}
