Product Description

The Dumas Nitrogen/Protein Analyzer is an advanced instrument for determining nitrogen and protein content in various samples through processes like high-temperature combustion, purification, reduction and thermal conductivity detection (TCD) following the standard Dumas method. With unparalleled efficiency and precision, the analyzer delivers results in under four minutes per sample, all while maintaining an environmentally friendly and safe operation process. Its intelligent design ensures seamless workflows for industries requiring fast and reliable analysis.

The first step includes a highly efficient 2-Stage combustion and oxidation process, whereby preliminary oxidation happens in a primary combustion tube, followed by digestion in the secondary combustion tube in presence of Pt catalyst and copper oxide.
This is followed by a 3-Stage Dewatering process, which effectively removes water for precise analysis using an electronic condenser and drying tubes.
Thereafter, nitrogen oxide is reduced to Nitrogen gas by the help of some effective reducing agents, which absorb the excess oxygen.
Finally, the High-Precision Thermal Conductivity Detector (TCD) accurately measures the nitrogen that was produced in the reduction stage.

Product FAQ's

How accurate are Dumas Protein Analyzers?

Dumas Protein Analyzers offer high detection accuracy and reproducibility due to advanced TCD detection and calibrated software, delivering reliable nitrogen and protein data.

Can the D50/D200 dumas analyzer integrate with software or lab systems?

Yes — many Dumas nitrogen analyzers include advanced software for data reporting, calibration management, and compatibility with lab information management systems (LIMS).

Do I need specialized training to use a Dumas Nitrogen Analyzer?

Basic training is recommended to operate the system optimally, including sample preparation, software use, and routine maintenance, but the automated design simplifies operation for most lab technicians.

What types of samples can a Dumas Nitrogen Protein Analyzer test?

It can analyze both solid and liquid samples, including cereals, seeds, meat, dairy products, animal feed, soil, fertilizer, and industrial fluids for total nitrogen and protein content.

Can the Dumas nitrogen analyzer be installed in standard laboratories?

Yes, the system is designed for standard lab environments and requires only basic utilities such as power, gas supply, and ventilation.

How is nitrogen detected by the Dumas method?

In the Dumas method, the sample is combusted at very high temperatures in the presence of oxygen. This process converts all nitrogen compounds in the sample into nitrogen gas (N₂). The resulting gases are purified to remove moisture, carbon dioxide, and other by-products. The purified nitrogen gas is then measured using a thermal conductivity detector (TCD), which quantifies the nitrogen content accurately and quickly.

Is the Dumas method better than the Kjeldahl method?

Yes, in many applications the Dumas method is considered better than the Kjeldahl method. The Dumas method is faster, fully automated, and does not use hazardous chemicals such as sulfuric acid or catalysts. It measures total nitrogen directly, offers higher throughput, and is more environmentally friendly. While the Kjeldahl method is still used in some regulatory applications, Dumas nitrogen analysis is widely preferred for routine, high-volume testing.
