Kjeltec Food Nitrogen Protein Analyzer
1.Feature and Description
NB9870 Series Full-automatic Kjeldahl Apparatus is the full automatic distillation-photometric titration analysis system researched based on the classic Kjeldahl determination. Totally 3 varieties of products for the series are basically same on property and operational approach, only different from partial functions.
Operating System of NB9870 Series
· Based on adopted 7.5-inch colored touch screen+Siemens CPU, the menu is Chinese-English switching mode, easy to operate and learn
· Operating system entering provides reliable sample registration and trace according to requirements of GLP.
· Reagent preparation method (process), instrumentation method, FAQ treatment stored on screen, for quick inquiry.
· Line-at-a-time printer (110mm), with more printing contents and facilitating report stick.

3.Usage and Application
As a classic method determining nitrogen, Kjeldahl determination is currently widely applied in determining niteogen content in soil, food, agricultural products, fodder and some other substances. When determining samples, the method consists of three steps: digestion—distillation—titrimetric analysis.
