Description

By using this elemental analyzer (Euro EA 3000) it is possible to determine the concentration of nitrogen, carbon and hydrogen in solid samples. The substance to be analysed is digested by an oxidative combustion of samples packaged in tin foil. The combustion takes place explosively in a highly oxygen enriched He atmosphere. Gases that generated during the combustion are led by the carrier gas (helium) into the separation column. CO₂, H₂O, N₂ and SO₂ are separated chromatographically within this column. The separation is based on the molecular sizes of the element compounds. For the determination a thermal conductivity diode (TCD) is used. The focus of this lab is the determination of total carbon and nitrogen (TC/TN), hydrogen (H), total organic carbon (TOC) (calculated) and inorganic carbon.

EA - Elemental Analysis
Total Organic Carbon (TOC) analysis is a well-defined and commonly used methodology that measures the carbon content of dissolved and particulate organic matter present in water. Many water utilities monitor TOC to determine raw water quality or to evaluate the effectiveness of processes designed to remove organic carbon. Some wastewater utilities also employ TOC analysis to monitor the efficiency of the treatment process. In addition to these uses for TOC monitoring, measuring changes in TOC concentrations can be an effective "surrogate" for detecting contamination from organic compounds (e.g. petrochemicals, solvents, pesticides). Thus, while TOC analysis does not give specific information about the nature of the threat, identifying changes in TOC can be a good indicator of potential threats to a system.
