VELP SCIENTIFICA Lab Solutions NDA 701 Dumas Nitrogen Analyzer Analysis in a flash with the VELP Nitrogen/Protein Analyzer - Fully Automated: totally unsupervised and independent of user’s capabilities - Flexible and Versatile: optimal for several sorts of sample - High Productivity: non-stop performance - Moderate Running Costs Food&Feed Line NDA 701 is the innovative VELP Scientifica solution for nitrogen/protein determination, using the Dumas method (also known as combustion method) and offering excellent performance on both solid and liquid samples. NDA 701 is revolutionary in terms of savings, thanks to TEMS™ technology: Time Saving - Unparalleled technology, results in 3-4 minutes Energy Saving - Excellent engineering, low consumption. Money Saving - Limited cost per analysis, less gas and reagents used (LoGas™ and DriStep™). Space Saving - Just one slim unit required for the whole analysis. NDA 701 is designed to last and to operate continuously, even 24/7, requiring minimal maintenance and working completely in safe conditions, without the use of hazardous chemicals. The optimization of the consumables lifespan combined with the their rapid replacement enhance the benefits of this revolutionary unit, able to perform extremely accurate analyses, with a very low detection limit (0.003 mgN) and superlative precision. The low RSD% shows the analysis reliability, underlining the great reproducibility and the quality of results. NDA 701 is completely controlled and operated by the DUMASoft™ Software, with most important information seen at a glance! The instrument includes an autosampler that can manage up to 30 samples (stackable to 117) both solids and liquids loaded in tin capsules in a completely automatic way and a kit of consumables for up to 1000 analyses, being immediately ready to use.

Constant Commitment to Knowledge Development In the Dumas combustion method, the encapsulated sample is burnt at a high temperature, in the presence of catalysts in a controlled oxygen atmosphere. The combustion gas, CO2, H2O, NOx, passes through the reduction furnace where NOx are reduced to N2. The H2O and CO2 are separated and the elemental nitrogen is measured with a Thermal Conductivity Detector (TCD). The whole procedure takes from 3 to 4 minutes. The samples need to be suitably homogenized, in order to maximize results’ precision and to analyze a representative part. CF = Combustion...
