Kjeldahl vs Dumas: Modern Protein Analysis

June 3, 2022

Since the 1800s, there have been two major methods of protein determination, the Kjeldahl and the Dumas methods. Both methods measure the nitrogen in a sample and use mathematics to convert that into the protein content. Though the Dumas method was older, the Kjeldahl method quickly took off in popularity due to its relative ease of performance. However, as new technologies developed, the Dumas method began gaining in popularity.

Unpack the Protein with the FP928

November 24, 2021

This Thursday, November 25, most Americans will be sitting down to a Thanksgiving meal, with approximately 95% eating some form of turkey. The National Turkey Federation (NTF) estimates that 46 million turkeys are eaten on Thanksgiving. At an average weight of 15 pounds per bird, this adds up to approximately 690 million pounds of turkey in a single day. But how much protein is in that turkey? LECO took a look.

Vertical vs Horizontal Furnaces: The Dumas Method for Protein Determination

September 24, 2021

Over the last thirty years, the Dumas combustion method for analyzing protein content in food has been gaining popularity against the classic Kjeldahl wet chemical digestion and titration method. 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.

Balanced Soil: Carbon, Nitrogen, and Sulfur Determination with the CNS928

January 21, 2020

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 easily through fast and precise analysis.
