Dumas Nitrogen/Protein Analyzers
NDA is the innovative VELP Scientifica solution for nitrogen/protein determination according to the Dumas combustion method for testing both solid and liquid samples.
- The most accurate & sensitive nitrogen & protein determination technique
- Instantaneous results – no long delays
- Environmentally friendly – no chemicals used, less residues & waste
- Conformity with multiple standards protocols
AOAC, ISO, AACC, AOCS, ASBC etc. -
Dumas analysis method
- Starts with a combustion stage to burn the sample. Obtains elemental compounds
- Water is removed by a first physical trap (DriStep™), positioned after the combustion
- Then by a second chemical trap
- Between the two, the elemental substances pass through a reduction furnace
- The auto-regenerative CO2 adsorbers let pass only the elemental nitrogen that is detected by the LoGas™ innovative Thermal Conductivity Detector (TCD) with no requirement for a reference gas -
VELP also offers consumables to improve the performance of the analyzer
