Vertical vs Horizontal Furnaces: The Dumas Method for Protein Determination
The Dumas method has several advantages over the Kjeldahl method: it is much faster, with much lower operating costs, no real safety issues, and no toxic waste produced. However, there is a debate over which of the two main approaches to the Dumas method is better: a vertical or a horizontal combustion furnace. Determined to settle the question on which…

Accommodate Lower-Level Nitrogen Samples in Food Materials with an Optimised Combustion Method
Did you catch our recent article on Food Navigator? Nitrogen content in food materials is necessary to measure when determining the total protein content. This measurement of nitrogen content can be performed using a classical wet chemistry method, but this tends to be a slow and tedious process. The combustion-based Dumas method has gained popularity in recent years as it…

Balanced Soil: Carbon, Nitrogen, and Sulfur Determination with the CNS928
Well-balanced crops require well-balanced soil. While carbon may be the most essential element for organic life, the right ratio of nitrogen and sulfur in the soil along with the carbon can really influence the speed and strength of plant development and growth. With a macro combustion carbon, nitrogen, and sulfur determinator such as LECO's CNS928, those ratios can be discovered…
