Unlike the Kjeldahl method, the Dumas method avoids toxic acids, making it safer for the environment and health. It is also simpler, faster, and more sustainable. Many food labs now prefer or supplement the Kjeldahl method with the Dumas method for protein determination in food and feed.

When determining total nitrogen (or protein) of a sample using LECO’s FP828, it is crucial to select the right sample container for the job. Several key considerations must be taken into account, like the sample mass capacities of the container, compatibility of the container with the matrix, ash production, and more.

In the world of plastics and polymers, precision matters. From everyday items to high-performance materials, the quality and consistency of polymers directly impacts their functionality. One often overlooked but critical aspect of polymer production is Nitrogen testing.
