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 method is more precise and offers the most advantages, LECO chemists analyzed many sample types in both an FP828 and an FP928.

For more information and a detailed breakdown of the results and a look at more of the samples used in this experiment, read Michael Jakob's article in the сентября 2021 issue of eFOOD-Lab International.
