The analyser is equipped with different detectors to follow Oxygen, Hydrogen and Nitrogen from very low content to high contents.  Oxygen and Hydrogen will be analysed with IR cells and Nitrogen by thermal conductivity.  Thanks to the resistive furnace almost all types of materials can be analysed.  For 1 g of sample (of steel for instance), the following compositions can be analysed: 

Based on different temperature slopes, the light element detected evolution will give some insight to indicate the activation energy for compounds dissociation and/or compound speciations.
