Kjeldahl Analyzer

A Kjeldahl nitrogen analyzer is a laboratory instrument designed to determine protein content in samples via the Kjeldahl method. Widely used in food, feed, agricultural, and environmental testing, it measures total nitrogen by digesting organic matter, distilling ammonia, and titrating the liberated nitrogen.

Key Features:

  1. High Precision: Ensures accurate protein quantification with minimal error margins.
  2. Automated Workflow: Streamlines digestion, distillation, and titration processes for efficiency.
  3. Multi-Industry Compatibility: Suitable for diverse applications, including quality control in food production and fertilizer analysis.
  4. Compliance: Meets international standards (e.g., ISO, AOAC) for reliable results.
  5. Durability: Built for robust performance in export markets, with corrosion-resistant materials.

Applications:

  • Protein analysis in foods (e.g., dairy, grains).
  • Feedstock evaluation for livestock.
  • Soil and fertilizer nitrogen content testing

    Product Details

    The export-grade Kjeldahl nitrogen analyzer is a laboratory instrument designed to determine the protein content in various samples (e.g., food, feed, agricultural products, and environmental samples) via the Kjeldahl method. Below is a structured introduction for international audiences:

    1. Core Functionality

    • Principle: Digests organic nitrogen in samples into ammonium sulfate, converts it to ammonia via distillation, and measures nitrogen concentration via titration.
    • Protein Calculation: Uses the formula % Protein = % Nitrogen × Conversion Factor (typically 6.25 for most food/feed samples).

    2. Key Technical Specifications

    • Detection Range: 0.1–20% nitrogen (adjustable per sample type).
    • Accuracy: ±0.1% (meets AOAC/ISO standards).
    • Sample Capacity: 1–20 samples/batch (depending on model).
    • Distillation Speed: 15–30 minutes per batch.
    • Power: 110–220 V (universal voltage for global use).

    3. Applications

    • Food Industry: Quality control of meat, dairy, grains, and processed foods.
    • Feed Production: Protein content analysis for livestock/pet feed.
    • Agriculture: Soil nitrogen testing and fertilizer efficacy evaluation.
    • Environmental Monitoring: Detection of nitrogen pollution in water/soil.

    4. Export Advantages

    • Certifications: CE, FDA, or RoHS compliance (as required by target markets).
    • Multi-Language Support: User interface available in English, Spanish, Arabic, etc.
    • Customization: Optional accessories (e.g., auto-titrator, waste neutralization system).
    • After-Sales Service: Global technical support and calibration services.

    5. Competitive Features

    • Durability: Corrosion-resistant materials for harsh environments.
    • Ease of Use: Automated workflows with touchscreen guidance.
    • Cost-Effectiveness: Low reagent consumption and minimal maintenance.
