Summary:
Kjeldahl method is a classical method for nitrogen determination. Kjeldahl method is widely used to determine nitrogen compounds in soil, food, animal husbandry, agricultural products, feed and
other products. The sample determination by this method requires three processes: sample
digestion, distillation separation and titration analysis
The company is one of the founding units of the national standard of “GB/T 33862-2017
full (semi-) automatic Kjeldahl nitrogen analyzer”, so the products developed and produced by
Kjeldahl nitrogen analyzer meet the “GB” standard and related international standards.

of the samples after the drop and pressure test. Compared with the traditional design, the
intelligent test is realized: the preset of multiple test parameters can greatly improve the
detection efficiency; the test mode of increasing pressure can be used to quickly obtain the
sample leakage parameters and observe the creep, fracture and leakage of the sample under
the stepped pressure environment and different holding time. Vacuum attenuation mode is
suitable for automatic sealing detection of high value content packaging in vacuum environment.
