Dumas Nitrogen/ Protein Analyzer
Inquiry NowProduct Description
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.
