Frequently Asked Questions

1 What is a Kjeldahl Analyzer?

A Kjeldahl Analyzer is an apparatus designed for determining the nitrogen content in organic and inorganic samples based on the Kjeldahl method.

2 How does Kjeldahl Analyzer work?

It works by digesting the sample with sulfuric acid, neutralizing the solution, distilling the released ammonia, and then quantifying it through titration or colorimetric methods.

3 What kind of maintenance is required by Kjeldahl Analyzer?

Regular maintenance includes cleaning the digestion and distillation units, checking for blockages, and calibrating sensors.

4 Can Kjeldahl Analyzer be used for protein analysis?

It is widely used for protein analysis by calculating nitrogen content and applying a conversion factor.

5 What types of samples can Kjeldahl Analyzer test?

It can test a variety of samples, including food products, feed, soil, wastewater, and pharmaceutical substances.

6 How is Kjeldahl Analyzer used in the food industry?

It is used in the food industry to determine protein content in products like meat, dairy, cereals, and beverages by analyzing nitrogen levels.

7 Can Kjeldahl Analyzer be used for environmental testing?

It is used in environmental testing to measure Total Kjeldahl Nitrogen (TKN) in soil, wastewater, and sludge to assess pollution levels.

8 How is a Kjeldahl Analyzer applied in pharmaceutical analysis?

It is applied in pharmaceutical analysis to determine nitrogen content in drugs and formulations, particularly in compounds containing amines or proteins.

9 How does Kjeldahl Analyzer support agricultural research?

It supports agricultural research by evaluating nitrogen levels in plant tissues, fertilizers, and soils to optimize crop nutrition and yield.

10 What role does Kjeldahl Analyzer play in regulatory compliance?

It plays a critical role in regulatory compliance by providing standardized nitrogen and protein data required by food safety and environmental agencies.
