JK9830 Automatic Kjeldahl Nitrogen Analyzer

Automatic Kjeldahl Nitrogen Analyzer JK9830

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

JK9830 automatic Kjeldahl nitrogen determination instrument is an analysis system developed based on the classic Kjeldahl nitrogen determination method, which can automatically distill and separate samples and analyze "nitrogen element" (protein) through external related technologies. Its method and manufacturing comply with the manufacturing standard of "GB/T 33862-2017 Fully (semi) automatic Kjeldahl nitrogen determination instrument" and relevant international standards
