LECO Solutions for Combustion Analysis

Protein is one of the most significant nutrients in cheeses. Accurate and precise determination of proteins helps to characterize nutritional and determine economic value.

Carbon and nitrogen are two of the primary nutrients of vital importance to the physiology of plants. Carbon content in soil plays in important role in the growth and development of plants. Plant foods or fertilizers with blends of multiple plant nutrients often including nitrogen. The amount of nitrogen in the fertilizer is optimized for the plant type that is being grown. The LECO 828 and 928 series of determinators can quantify the amount of carbon and nitrogen in soils, fertilizers, and plants. This webinar will focus on quantifying both carbon and nitrogen in these matrices.

The presentation will outline TOC determination in soil using two different approaches. First, we will explore the use of acid treatment of the soil to remove carbonates followed by analysis using conventional combustion techniques. Next, we will explore using a ramped furnace temperature approach to differentiate organic and inorganic carbon species. TOC results from both approaches will be presented. Jeffrey Gast

Sulfur is one of the essential macronutrients required for plant growth, aiding the formation of amino acids and proteins, as well as chlorophyll formation. Initiatives to reduce sulfur emissions have led to less sulfur being deposited in soil, causing an increased use of sulfur-containing fertilizers; resulting in an increased demand for sulfur determination in fertilizers, soils and plant tissue. This webinar will outline several combustion based approaches for sulfur determination in these materials. Lloyd Allen
