Chemical Analysis Instruments

This category includes a wide range of chemical analysis instruments used for the quantitative and qualitative determination of substances in laboratory samples. These products are commonly applied in food quality testing, agricultural and environmental analysis, pharmaceutical development, and academic research.


Available product lines include:

  • Kjeldahl Nitrogen Analyzers – for determining nitrogen and protein content in compliance with international standards.

  • Digestion Furnaces – provide controlled heat for sample digestion, supporting nitrogen and elemental testing workflows.

  • Fat Analyzers – used to measure fat content in food, feed, and agricultural products, including Soxhlet and rapid extraction systems.

  • Fiber Analyzers – designed for crude fiber and dietary fiber determination in grains, feed, and plant materials.

  • Gas Analyzers – suitable for detecting specific gases such as sulfur dioxide and other volatile compounds.

  • Ion Analyzers – instruments for analyzing ionic concentrations in water, soil, and chemical solutions, including automated cation exchange systems.

  • Near-Infrared Analyzers (NIR) – provide rapid, non-destructive analysis of moisture, protein, starch, and oil content in grains and food products.

  • Exhaust Gas Treatment Units – essential for neutralizing acid or toxic gases released during digestion or chemical reactions, ensuring laboratory safety and compliance.

  • Atomic Spectrometers & Elemental Analyzers – essential for precise detection and quantification of metal and non-metal elements in liquid or solid samples, supporting applications in environmental monitoring, food safety, pharmaceutical analysis, and materials research.


These instruments are essential tools for laboratories that require consistent performance, precise results, and compatibility with standard testing protocols.
