High precision leads to higher quality 

In chemistry, the term quantitative elemental analysis is used to describe the quantitative determination of the elements carbon (C) and hydrogen (H) as the main constituents of all organic substances, as well as the most important heteroatoms: nitrogen (N), oxygen (O), sulfur (S), more rarely also phosphorus (P) and the halogens (F, Cl, Br, I).

Commercially available instruments of CHNS elemental analysis work according to the principle of the so-called combustion analysis. A precisely weighed sample quantity is transferred via a sample lock into a combustion tube and burned at continuous temperatures of up to ~1400 °C with the addition of pure oxygen (O2). The released gaseous oxidation products (analysis gases) are then passed through the complete analyzer by means of an inert carrier gas. To reduce the nitrogen oxides (NOx) formed during combustion to nitrogen (N2) and to remove any excess O2 from the analysis gas, the analysis gas is then passed through a packing of hot copper (chips or granules). Thus, only the analysis gases N2, CO2, H2O and SO2 remain in the He carrier gas flow. At this point ULTRA.sens® and INFRA.sens® are used for the selective and quantitative determination of carbon (as CO2) and sulfur (as SO2). Based on the measured values, the components of the solid sample can be reliably determined.
