Kjeldahl nitrogen analyzer is a commonly used laboratory analytical instrument. In the Kjeldahl method for determining protein content, one crucial step is titration. Titration is both a chemical experimental procedure and a method of quantitative analysis.

How to Choose the Titration Mode of Kjeldahl Apparatus?

The Kjeldahl method for determining the endpoint utilizes acid-base neutralization titration. During titration, as the acid in the mixture increases, the endpoint is approached. Theoretically, the smaller the amount of acid added at the endpoint, the more accurate the result. However, if very small amounts of acid are added each time, the titration time will be very long.

Kjeldahl nitrogen analyzers with dual-mode titration support two titration modes: coarse titration and fine titration. Use the coarse titration mode at the beginning of the titration to save time, and use the fine titration mode near the endpoint for more accurate results. Whether an instrument has dual titration modes is an important indicator of its performance when selecting a nitrogen analyzer.
