for precision materials handling, power plant, for the food industry, for the mining industry, Dumas method
5E-TCN2200 Dumas Protein/Nitrogen Analyzer, is able to perform precise nitrogen analysis and protein determination, known also as “Combustion method”, it ensures precise results in few minutes, breaking down the sample into its elemental compounds. Substances produced, such as H2O, O2 and CO2, are trapped and removed, in order to ensure the correct detection of the nitrogen.

1. Maximum Efficiency
1) High throughput: standard auto loader for 35 samples per layer, stackable to 4 layers available.
2) Closed-loop water circulation assures the purity of water system without any additional solution.
3) Dual-stage furnace system with pure oxygen flow to ensure the complete combustion of all samples.
2. Good Environment Adaptability
1) Optimum gas circuit provides good gas tightness of the system.
2) O-ring free from heat resource.
3. Minimum Consumption
1) To determine N by TCD.
2) Saving time, gas and reagent: only 5.5ml blended gas needed to be analyzed.
4. Unattended Operation
The operator is limited to just adding sample to auto sample loader. Then the instrument will finish the test, cool down and shut off automatically.
Analysis Time: 4-6 mins, depending on sample combustion conditions
Measurement Range: Nitrogen: 0.04mg-50mg
Sample Mass: Up to 1000mg, depending on sample matrix
Furnace Type: Resistance furnace, max. temp 1050℃
coal, biomass, food, feed, soil, liquids and etc.
