TOC Total Organic Carbon analysis

In addition to our ISO 17025 accredited CHNOS analysis services, our laboratory also specialises in Total Organic Carbon (TOC) analysis*, both in solids and in waters.

TOC analysis in solids

TOC analysis is the measurement of organic carbon, mainly in soils and sediments, but in theory TOC analysis is applicable to any solid substance containing a mixture of organic and inorganic carbon.

At Elemental Lab, the method used to measure TOC in solids is to differentiate between TC, TIC and TOC (Total Carbon, Total Inorganic Carbon and Total Organic Carbon) using combustion elemental analysis.

TOC analysis in waters (new service as of 2025)

The measurement of organic molecules in water is vital due to the impact they could have on the environment, human health and manufacturing processes.

Elemental Lab provides a comprehensive service for analysis of TOC and related parameters in waters.
