Comparison of Acid Type for Removal of Carbonates from Soil for Total Organic Carbon Determination using the LECO C832 and CN928

Total Organic Carbon (TOC) is a key indicator of soil quality as it influences nutrient availability, microbial activity, and carbon sequestration. This webinar presents a detailed overview of TOC determination in soils using acid digestion—specifically employing sulfurous and hydrochloric acids to remove inorganic carbon. The chemical principles behind the digestion process and sample preparation techniques will be featured.

A special focus will be given to the use of the LECO C832 Carbon Analyzer, a high-precision instrument designed for accurate and efficient carbon quantification. Attendees will learn how to integrate this analyzer into their workflow, interpret results, and ensure data quality. This webinar offers both theoretical insights and practical guidance for reliable TOC analysis in diverse soil environments.
