Kjeldahl Digestion Units
The digester is a widely used instrument in laboratories performing nitrogen analysis for diversified applications in food&feed, beverage, environmental, chemical and pharmaceutical industries.
- The most common nitrogen & protein determination technique
- Applications in multiple markets
Food & Feed / Beverages (nitrogen, protein, Total Kjeldahl Nitrogen)
Environmental (COD, Total Kjeldahl Nitrogen)
Chemical and Pharmaceutical (organic nitrogen) industries - Conformity with multiple standards protocols
AOAC, ISO, EPA, DIN etc. - Kjeldahl analysis method
– Break down the bonds that hold the polypeptides together
– Convert them into simpler molecules such as H2O, CO2 and NH3
– Reactions can be speeded up
by higher temperature used during digestion
by the presence of acid, salt and catalysts
– During the reaction corrosive, toxic gases are created
for example SO2 and SO3
– Gases can be neutralized using the VELP
Dedicated pump, able to aspirate gases and vapors
Scrubber to capture final traces of toxic fumes - VELP also offers consumables to speed and and simplify digestions
