Description
Technical field
This application involves a kind of kjeldahl apparatus.
Background technique
Kjeldahl's method is a kind of method for measuring nitrogen pool in compound or mixture.I.e. in the condition for having catalyst
Under, organic nitrogen is all transformed into inorganic ammonium salt with concentrated sulfuric acid sample digestion, then converts ammonia for ammonium salt under alkaline condition, with
Steam distillation comes out and is excessive borate absorption, then with standard titration with hydrochloric acid, so that it may calculate the nitrogen quantity in sample.By
It is more constant in protein nitrogen content, protein content can be calculated by its nitrogen quantity, so method is classical protein quantitation methods.
