 NDA 702 Nitrogen Dumas Analyser

  • Dumas Combustion method for measuring nitrogen
  • Built-in 30 place auto-sampler
  • Can stack 6 carousels
  • Argon or Hekium Carrier Gases

Combustion Reactor (CF):    . allows combustion at 1030 °C in order to break all of the sample into its elemental substances.

Physical Water Trap (WT1):   the maintenance-free DriStepTM cooler permits 99% of water to be removed.

Reduction Reactor (RF):        enables the elimination of unwanted compounds and oxygen, transforming NOx into N2. 

Chemical Water Trap (WT2):   eliminates the residual water.

CO2 Regenerating Adsorbers (CO2):    used to get rid of all the CO2. Auto-regenerating, maintenance-free system.

Innovative TCD (TCD) LoGasTM :     determines nitrogen content without the need for a reference gas. Maintenance-free

The autosampler can hold up to 116 samples (both solids and liquids) loaded in tin capsules

The samples need to be accurately homogenized, in order to maximize the results precision and to achieve a representative analysis.

Fibre Analyser

The FIWE 3 is a three-position extractor suitable for raw fiber determination, conventionally known as an indigestible residue. Rapid analysis, reliable results and high reproducibility are some of the most relevant benefits of these units which are ideal for the following applications:
- total raw fiber determination (Weende)
- neutral detergent fiber and acid detergent fiber determination (NDF and ADF, Van Soest)
- acid detergent lignin determination (ADL, Van Soest)
- different fractions of fiber (cellulose, hemicellulose and pectin)

  • Automated digesters: 3 and 6 Tube Digesters
