  12. 12. LABLING : Type of Sample: Date : 02-05-2012 Code :98766 Tel :+56789
  13. 13. GRAINDIG / MIXING:
  14. 14. Fat EXTRACION :The fat is obtained by the direct extraction ofthe sample with warm light petroleum ether ,boiling range of 40-60 C .The solvent isremoved and the dry fat weight.
  15. 15. FAT DIRECT THROUGHSOXHLET:
  16. 16. Crude Fiber:The sample is boiled for 35 minutes in dilutedsulphoric acid. After filtration and washingthe sample is boiled again for 35minites indiluted potassium hydroxide .After filtrationwashing and drying the residue is ashed at500 C .The difference in weight before andafter ashing is called crude fiber ..
  17. 17. .
  18. 18. Moisture:The sample is dried out at 103 °C( ± 1 °C ) for 4 hours to a constant weight .Theweight difference represents the watercontent..
  19. 19. Atomic Absorption SpectrophotometerSample are boiled with HCL ,filtrated ,whennecessary diluted and than measured byAtomic Absorption Spectrophotometer atspecific wavelengths per element..
  20. 20. Atomic Absorption Spectrophotometer.
  21. 21. chloride testDetermination of chloride in compound feedsand raw materials by potentiometric titrationwith silver nitrate using the Ag-electrode.
  22. 22. CRUD PROTEIN ACCORDINGKJELDAHLThe sample is mineralized by concentrated sulphoric acid in the presence of a catalyst. in this way it is transformed into ammonium sulphate. After an addition of hydroxide ,the solution is distilled and ammonical nitrogen is caught in diluted acid and determined by the titration method.
