INSPIRION CHN

Method Overview

Elemental analysis for Carbon, Hydrogen, and Nitrogen (CHN) is a fundamental technique for characterizing the chemical composition of organic and inorganic materials. It provides critical data for quality control, research, and regulatory compliance across diverse industries.

From determining the purity of pharmaceutical compounds and polymers to analyzing the nutritional content of soils, feed, and biomass, CHN analysis offers rapid, precise, and reliable quantification of these key elements, forming the basis for formula calculation, process optimization, and material identification.

INSPIRION CHN Elemental Analyzer

The INSPIRION CHN is a high-performance elemental analyzer built on the proven, classical Dumas-Pregl method. It provides rapid, simultaneous determination of Carbon (C), Hydrogen (H), and Nitrogen (N) in a wide variety of solid and liquid samples. With its robust design, intelligent automation, and advanced detection system, it delivers accurate and reproducible results trusted by laboratories worldwide.

Key Features & Working Principle

The analyzer operates through a fully automated four-zone process:

  1. Combustion Zone: Samples are introduced via an integrated autosampler (standard 39-position, expandable to 78) in special capsules. They are completely combusted in an excess of pure oxygen with catalysts.

  2. Gas Control Zone: The resulting gas mixture is monitored for complete combustion, normalized, and prepared.

  3. Separation Zone: Interfering gases are removed.

  4. Detection Zone: Three separate detectors provide ultimate accuracy and flexibility:

    • Infrared (IR) Detectors: For precise quantification of Carbon (as CO₂) and Hydrogen (as H₂O).

    • Thermal Conductivity Detector (TCD): For accurate measurement of Nitrogen (as N₂) after CO₂ and H₂O absorption.

This multi-detector design allows the analyzer to be flexibly configured for CHN, CN, CH, or N-only analysis modes.

Key Advantages

  • High Accuracy & Sensitivity: Two-stage combustion with CO₂ conversion monitoring ensures complete sample oxidation. Separate detection for each element eliminates cross-interference.

  • Operational Efficiency: Fast analysis (~4 minutes), low carrier gas consumption, and automated furnace heating/cooling cycles.

  • Versatile Configurations: Use as a full CHN analyzer or as a dedicated, high-speed nitrogen/protein analyzer—a modern alternative to the traditional Kjeldahl method.

  • Advanced Software: User-friendly PC software allows for easy method setup, automated gas-saving modes, customizable reporting, and seamless data export to LIMS.

Applications

The INSPIRION CHN analyzer is essential in numerous fields:

  • Chemical & Pharmaceutical Industry: Purity verification of organic compounds, solvents, polymers, and active pharmaceutical ingredients (APIs).

  • Petrochemical, Coal, & Fuel Analysis: Characterization of crude oil, coal, biofuels, and lubricants.

  • Agriculture & Environmental Science: Analysis of soils, fertilizers, plant biomass, compost, and feed for nutrient content and carbon sequestration studies.

  • Material Science: Characterization of ceramics, catalysts, composites, and advanced materials.
