Dumas nitrogen analyzer

Instrument Introduction

Based on the classic and mature technology of Italian elemental analysis, combined with other highly recognized methods in the domestic market, the Liman team has accumulated valuable experience in the field of elemental analysis applications for over 20 years and has a customer base of thousands. With years of dedication, they have developed the new Dumas combustion protein analyzer EA3507 to meet the existing analysis needs of domestic customers. Its comprehensive performance and quality have been accepted and recognized by a large number of users.

The EA3507 Dumas Combustion Protein Analyzer is widely used in scientific research, customs, grain inspection, quality inspection, food, chemical and other testing institutions in universities. It can test the total nitrogen/protein content in solid or liquid materials such as fertilizers, grains, feed, grains, dairy products, meat products, fermented products, biomass, soil, and vehicle urea.

The EA3507 Dumas Combustion Protein Analyzer is based on the principle of dynamic oxygen injection combustion. Compared with traditional Kjeldahl nitrogen analyzer, it greatly shortens the analysis time and does not require any toxic chemicals. The sample undergoes sufficient combustion oxidation-reduction reactions under the action of a catalyst, and nitrogen oxides are ultimately reduced to N2, which is then detected by a TCD detector.

Main Features
Pure oxygen directly reaches the surface of the sample, and two-stage combustion is more effective;
Efficient three-level water removal technology, equipped with color changing indicators;
Dual MFC precise control of oxygen and helium, stable flow rate and gas saving;
High sensitivity intelligent electronic monitoring system, fast and accurate leak detection;
Intelligent shutdown and gas shut-off technology, no need for on duty, safe and efficient.
