Application Industries of HGK-57 Fully Automatic Kjeldahl Nitrogen Analyzer

Shanghai Heguan HGK-57 Fully Automatic Kjeldahl Nitrogen Analyzer, with its high precision, full automation, and robust data traceability capabilities, is primarily applied in the following industries with stringent requirements for protein or nitrogen content testing:
Main Application Industries
1. Food and Agricultural Product Processing Industry
Application: This is a classic and widely used field. It is used to detect the protein content in various foods, which is a key indicator for measuring nutritional value, quality grading, and pricing.
Specific Objects:
Dairy Products: Milk, milk powder, yogurt, etc. (protein content is a core quality indicator).
Grains and Feed: Wheat, rice, soybean meal, corn, and various compound feeds.
Meat Products: Fresh meat, meatballs, sausages, canned goods, etc.
Beverages and Condiments: Protein beverages, soy sauce, monosodium glutamate, etc.
2. Feed Industry
Application: Precisely determining the protein content in feed raw materials and finished feed is a critical step for scientifically formulating feed, ensuring livestock and poultry nutritional needs, and controlling production costs.
Specific Objects: Fish meal, soybean meal, rapeseed meal, and other protein raw materials, as well as various livestock, poultry, and aquatic feeds.
3. Agriculture, Soil, and Plant Science
Application: Used to analyze the total nitrogen content in plant tissues such as leaves, seeds, and straw to assess plant nutritional status and study nitrogen fertilizer utilization efficiency. It can also be used for soil nitrogen content analysis to guide scientific fertilization.
Specific Objects: Plant samples, soil samples.
4. Chemical and Fertilizer Industry
Application: Used to determine the nitrogen content in chemical products and the nitrogen content or purity of fertilizers (such as urea, ammonium nitrogen fertilizers) for quality control and product inspection.
5. Pharmaceuticals, Biotechnology, and Research Institutions
Application: In biopharmaceutical research and development, it is used to determine the nitrogen/protein content in biological samples (e.g., cell cultures, tissue homogenates, protein purification products). Its robust data audit trail functionality (audit trail) is particularly compliant with the regulatory requirements of GMP/GLP laboratories.
Specific Objects: Biological agents, research samples.
6. Environmental Monitoring and Testing Institutions
Application: Used to analyze Kjeldahl nitrogen in water samples (e.g., wastewater, surface water), which is the sum of organic nitrogen and ammonia nitrogen, serving as an important indicator for evaluating water pollution levels. Third-party testing companies also use this instrument to provide impartial testing services for the aforementioned industries.
Why is the HGK-57 Particularly Suitable for These Industries?
High Precision and Compliance: Its excellent reproducibility (RSD <0.5%) and recovery rate (>99.5%) ensure accurate and reliable test results, meeting national or international standards (e.g., Chinese National Standard GB/T 5009.5) across various industries. The features of cloud-based data storage, immutability, and traceability perfectly align with modern laboratories' requirements for data integrity and audit trails.
High Efficiency and Automation: Fully automated processes from liquid addition, distillation, titration to cleaning significantly enhance testing efficiency, making it especially suitable for quality control centers, enterprises, and testing institutions with large sample volumes.
Broad Applicability: A wide measurement range (0.1-210mg nitrogen) and adjustable distillation power enable it to handle various samples from low-protein to high-protein content.
In summary, the Shanghai Heguan HGK-57 is a high-end nitrogen analyzer designed for modern, high-standard laboratories. Its applications cover all fields requiring precise determination of nitrogen/protein content, from routine food quality inspection to cutting-edge biopharmaceutical research and development.
