EA

The Elemental Analysis (EA) technique operates through a multi-step process. Initially, the solid or liquid sample is introduced into a combustion reactor where it undergoes complete combustion or pyrolysis in an oxygen-rich environment at high temperatures, typically around 1000°C. This process ensures that the sample is fully broken down into its elemental components. Subsequently, the resulting combustion gases, which contain the analytes of interest such as carbon dioxide (CO2), water (H2O), nitrogen (N2), and sulfur dioxide (SO2), are directed towards a gas separation and detection system. Here, these gases are separated and identified using specific detectors, including thermal conductivity detectors (TCD), infrared detectors (IR), or other specialized detectors, each tailored to detect particular elements or compounds. Finally, the concentrations of these elements are quantified by comparing the detector signals with those of calibration standards. This quantification process accounts for the sample’s weight or volume, enabling precise determination of the elemental composition of the sample.
