Combustion analysis is an analytical technique used to determine the content of carbon (C), sulfur (S), nitrogen (N), oxygen (O), and hydrogen (H) in solid materials. It is widely used in the steel, mining, cement, and environmental industries.

During the analysis, the sample is combusted or melted under controlled conditions. The resulting gases are then quantitatively measured using dedicated detection methods, allowing even very low concentrations of individual elements to be determined with high accuracy.

In the metallurgical industry, the precise determination of carbon and sulfur is particularly important, as these elements have a significant influence on the properties of metallic materials. In the cement industry, carbon and sulfur contents are also routinely monitored as part of quality control.

The quality of the analysis depends largely on representative sampling and reproducible sample preparation. Automated systems minimize operator influence and improve the consistency and comparability of analytical results.

HERZOG offers integrated solutions for the complete automation of sample preparation and combustion analysis. These include the HUST system for the automatic punching of samples for combustion analysis, the Granular Chips Module of the HS-F 1000 for producing automatically handleable metal chips, and the CNSLab for the fully automated loading and integration of combustion analyzers. Together, these solutions enable a continuous, reproducible, and largely operator-independent workflow from sample preparation to the final analytical result.
