Accurate Nitrogen Analysis with the Kjeldahl Auto Analyzer

The Kjeldahl Auto Analyzer is a cornerstone of protein and nitrogen determination in laboratories across the globe. Based on the classic Kjeldahl method, this automated system simplifies the measurement of nitrogen in organic and inorganic compounds—making it an essential tool for food testing, agricultural analysis, environmental monitoring, and more.

What Is the Kjeldahl Auto Analyzer?

This Laboratory instrument automates the three main steps of the Kjeldahl process:

1. Digestion of the sample to convert nitrogen to ammonium sulfate.

2. Distillation of the ammonium into a boric acid solution.

3. Titration to quantify nitrogen content.

By automating these steps, the Kjeldahl Auto Analyzer improves throughput, accuracy, and safety while minimizing operator involvement.
