The Kjeldahl method is a widely used analytical technique for determining the protein content in a sample by measuring its nitrogen content. Since the nitrogen content in proteins remains relatively constant, this method provides a reliable way to estimate protein levels. The instrument used for this process is commonly referred to as a Kjeldahl analyzer, or more specifically, a nitrogen analyzer, protein analyzer, or crude protein analyzer. This method was first developed by Johan Kjeldahl in 1883 and has since become a standard in many scientific fields.
In addition to its traditional use in food analysis, the Kjeldahl method is also extensively applied in biochemical research, environmental testing, and agricultural studies. It helps scientists and researchers accurately determine the protein content in various samples, such as soil, feed, and biological tissues. The micro-Kjeldahl method is a modified version that requires smaller sample sizes, making it ideal for applications where only limited material is available.
Whether you're working in a laboratory, a food processing facility, or an academic institution, the Kjeldahl instrument plays a crucial role in ensuring accurate and consistent results. At Shanghai Xinzhuang Instrument Co., Ltd., we offer a range of advanced Kjeldahl analyzers designed for precision, efficiency, and ease of use. Our professional team is always ready to provide detailed guidance and support to help you choose the right equipment for your needs.
