Automatic Azotometer Kjeldahl Analyzer Applied To The Test Of Protein/Nitrogen Content
Kjeldahl Apparatus Profile
QKD-3000 Automatic Kjeldahl Analyzer is designed primarily for Kjeldahl analysis, which is widely applied to the test of Protein/Nitrogen content in grain and oils, drink, fodder, soil, chemical fertilizer, pharmacy and residuals as well as the test of ammonium salt, volatile fatty acids or alkali in chemical products.
Brand new long-service-life design, advanced computer intelligent control, colored liquid crystal touch screen operation, and Chinese menu-driven interface with man-machine conversation functionality are integrated in the design of SKD-1000. It is capable of automatically accomplishing a series of standard processes including the input of sample’s weight, adding acid, alkali and diluents, distillation, titration and printing. Replacing traditional complex potentiometry and simplex colorimetry, titration judged by international standard color method is employed, which guarantees the accuracy, performance and operation of the instrument. It has several proprietary intellectual property rights and patents and some technologies initiate in China and have reached advanced level internationally.
Kjeldahl Apparatus Technology Advantage
Machine shell is made of ABS plastic, which prevents the problem of corrosion "never rust"(Its working environment is full of strong acid and alkali).
Special rubber connectors made of corrosion-free material and high temperature resistance and alkali/acid resistance plastics are used to connect the inner tubes, whichenhance the accuracy and operating life of the instrument without replace for 3 years.
Adding alkali or acid with constant pressure on the alkali bucket from pressure pump extrudes alkali liquor, which exterminates corrosion of the alkali pump and ensures the accuracy of alkali/acid addition. Moreover, RSD of distillation is enhanced and the fault rate is efficiently reduced. Over-pressure protection of the inner tube ensures the balance of steam output and effectively prevents the suck-back of the samples.
Its single chip computer control and the setting of automaticcally adding alkali/acid, distilling and storing data ensure the testing process to be much faster, more accurate and stable.
More than 10 different programs of pre-heating, cleansing, alkali/acid addition are available.
Cleaning control system can intelligently clean the distiller and alkali/acid pipelines, making the distillation more thorough and accurate.
