TFTAK expands analytical capabilities: Dumas and Kjeldahl methods now under one roof

TFTAK has acquired Dumas equipment for fast nitrogen and protein determination in feed, food, grain, and innovative ingredients. The new capability complements the Kjeldahl method already in use and enables protein analysis based on two industry standards.

Protein and nitrogen analysis in the industry is based on two established standard methods: the Kjeldahl method and the Dumas method. The Kjeldahl method has been TFTAK’s trusted standard, while the addition of the automated Dumas, or combustion, method broadens the analytical scope for protein analysis.

Having both methods available in a single laboratory enables TFTAK to perform both traditional reference testing and high-speed serial analyses. This supports data convergence and enables cross-method quality control.

Key benefits of Dumas equipment for our clients:

• analyses in compliance with international ISO and AOAC standards for different matrix types;

• reduced turnaround times, or TAT, for urgent samples;

• cross-method quality control for protein and nitrogen analysis;

• Dumalyzer N/Protein’s analysis time is 3–4 minutes per sample, RSD (CRM) of 0.5%, and LOQ as low as 0.06% protein.

TFTAK continues to invest in analytical infrastructure to provide partners with an expanded testing scope and analytical services.
