TOC Determination in Soil Utilizing Temperature Differentiation Method

Presented by: Jeffery Gast [LECO Corporation]

Accurate quantification of Total Organic Carbon (TOC) in soil is critical for environmental monitoring, soil fertility, water retention, and promoting biodiversity. The LECO RC612 Multiphase Carbon Analyzer, referencing the DIN 19539 standard, offers a robust and precise methodology for differentiating and quantifying carbon species in soil sample types.

This webinar will explore the operational principles of the LECO RC612, highlighting its high-temperature combustion and infrared detection capabilities and how it seamlessly integrates with the DIN 19539 parameters. Emphasis is placed on the method’s ability to distinguish between TOC, ROC (Residual Oxidizable Carbon), and TIC (Total Inorganic Carbon) through temperature-programmed decomposition, ensuring compliance with regulatory standards and enhancing analytical reliability.

Data will illustrate the instrument’s performance across various samples of soils. Attendees will gain insights into method optimization, calibration strategies, and data interpretation, making this session valuable for laboratories seeking to improve their carbon analysis workflows.
