Kjeldahl Nitrogen Analyzer Distiller

LC-KDN

The KDN Series Nitrogen Analyzer Distillers are automated nitrogen distillation systems designed based on the classical Kjeldahl method. These instruments measure protein content by determining nitrogen levels in samples, leveraging the principle that nitrogen content in proteins remains constant.They are widely recognized as Kjeldahl Nitrogen Analyzers due to their adherence to this established methodology.
