food analysis equipment:-
Kjeldahl Block Digestion Apparatus for protein/nitrogen analysis in Food ,Feeds ,Flour etc:
The Kjeldahl method consists of three steps: 1) DIGESTION of the sample in sulphuric acid with a catalyst. The nitrogen contained in the sample is converted to ammonia; ammonium sulphate being formed. 2) DISTILLATION of ammonia released from ammonium sulphate by addition of an excess of sodium hydroxide; ammonia being trapped in a trapping solution (sulphuric acid). 3) BACK-TITRATION of the excess of the trapping solution.
Atomic Florescence Spectrometer (AFS)
Atomic Fluorescence Spectrometer , AFS for heavy metals analysis such as As, Hg , Cd ,Pb etc.
Model AFS-8230
Kjeldahl Method or Kjedahl Digestion
Kjeldahl Kjedahl Digestion is a method in chemistry for the quantitative determination of Nitrogen in chemical and food substances developed by Johan Kjeldahl in 1883.
