Peiou digestion furnace in the application of organic-inorganic fertilizer materials

Provisions in GBT 17767-2008 detction method of organic-inorganic fertilizer materials.Alone in the digestive process mentioned bubble phenomenon appeared in the process of digestion, Suggestions to reduce heating intensity does not produce bubbles after also continue to heat, it is difficult to achieve this in other equipment in the actual operation.
       And the agriculture department NY/T 1977-2010 for total nitrogen, phosphorus and potassium content of water soluble fertilizer recognized measurement of kjeldahl determination for arbitration law, more detailed rules for the different ways you can sample processing.The mentioned sample will be smoke, while others appear a large number of bubble phenomenon;The more complex form, and some samples in ammonia digestion time is longer.
        These phenomena are clearly reflected in the national standard and the department of agriculture line standard, and repeatedly the digestible furnace is very good to solve the above problem:
    1: sample digestion with bubbling phenomenon of residuals, the solution in provisions can not be fundamentally eliminate these phenomenon, caused the sample test result is not accurate.64 phase of the program (peiou's digestive furnace temperature can be adjusted according to the nature of the sample set in stages of temperature adjustable heating rate, in particular, to eliminate the phenomenon of residuals in the digestion of the sample. (also: organization developed a explosion-proof boiling device, further can put an end to residuals phenomenon of the samples produced).

   2: sample digestion process of smoke, polluting the laboratory environment, and the presence of the toxic fumes can harm the laboratory staff's health.(pei's infrared furnace digestion standard stainless steel drainage device, to eliminate the smoke escape)
    3: furnace digestion time is too long, cooling time is long, reuse trival, waste a lot of time on the process of digestion.(pei's infrared absorb furnace under the condition of the low power with the method of the infrared radiation heating, time-consuming, solved the other digestive furnace cooling time is bad)
      In conclusion, Peiou's digestive furnace used in response to fertilizer industry users automatic kjeldahl nitrogen determination apparatus can be effective to solve in the use of smoke, foam, residuals, and time-consuming long, suitable for processing in front of the fertilizer nitrogen fertilizer industry recovery.
