Product Application

Kjeldahl nitrogen determination method is a classic method for determining nitrogenAt present, the Kjeldahl method is widely used to determine nitrogen-containing compounds in soil, food, animal husbandry, agricultural products, feed, and other fields. When using this method to determine samples, three processes are required: sample digestion, distillation separation, and titration analysis

JQ9870DigiPREP TKN SystemsIt is a fully automatic distillation developed based on the classic Kjeldahl nitrogen determination method——Titration technologyColor methodDetermining the endpointThe method and manufacturing of the "nitrogen element" (protein) analysis system comply with《GB/T 33862-2017 Fully (Semi) Automatic Kjeldahl Nitrogen Analyzer "Manufacturing Standard andInternational relevant standards
