Automated Dumas analysis for quality control in food and feed laboratories. Full control of your data with remote surveillance option.

Sample type

Food and animal feed, liquid, paste and solid Samples




Dumas method – quick combustion of a sample in a pure oxygen atmosphere and analysis of all resulting nitrogen. Helium is used as carrier gas.

Key Features

Reliable Dumas with reduced work

Free your laboratory resources. With Dumatec™ 8000 removal of CO2 is done automatically with the patented self-regenerating adsorption trap within a six position carousel.

Easy to use auto sampler

A smart auto sampler disc system gives you batch handling flexibility. Up to three discs can be loaded simultaneously allowing up to 117 samples to be analysed unattended.

Three-stage water filtering system

The unique three-stage water removal system increases the lifetime of the water trappacking many times. The by-product water (H2O) is separated from the gas mixture by three water traps – F1, F2 and F3. F1 is a water condensation tube. F2 is a Perma Pure gas membrane. F3 is a silica gel water trap.

Everything You Need to Know About Foss Dumatec™

Foss Analytical

FOSS creates end-to-end solutions that secure and improve food quality. From raw material to finished product. Our analysis instruments refine measurements into information management that enables businesses to run intelligent data-driven productions with less waste and bigger yields. Controlling cost and quality across all sectors and value chains, we help food and agricultural producers limit the number of human errors, scale their business faster and reduce manual labor as well as labor costs. We call it analytics beyond measure.

We cover these food and agricultural industries: Dairy, Feed and Forage, Grain, Flour Milling & Oilseed Processing, Laboratories, Meat, Raw Milk Testing and Wine.

Over the last 60 years, we have made it our business to define the standard of analytical solutions for the food and agricultural industry. We pioneered advanced analysis for the challenging production environments in the 1960’s, and we were the first to integrate chemical composition analysis in process lines. Now our resolve and ambition have also made us the international benchmark in the field of chemometrics and real time analytics.
