Applications

Technical Specifications

Analytical Principles and Methodological Compliance

This system implements controlled tube furnace oxidation, converting all organically bound hydrogen in solid matrices into pure water vapor, while carbon compounds are fully oxidized to carbon dioxide gas. The gaseous combustion effluents are systematically scrubbed of acid halides, sulfur dioxides, and nitrogen oxides using specialized internal chemical reagents across dual temperature-controlled zones before reaching the calibrated absorption media.

The thermal profiling of the equipment—featuring a primary furnace zone stabilized at 800°C ± 10°C and a secondary conversion zone regulated at 300°C ± 10°C—ensures complete sample dissociation without unburned residues or tar formation. The microcontroller instantly compensates for ambient variations, applying certified correction formulas to recalculate raw signals into direct milligram readings and final percentage mass fractions. By meeting every rigorous requirement established in GB/T 476-2001, laboratory managers can integrate this hardware into international testing workflows without recalibrating benchmark methodologies.

Sample Handling and Operational Optimization

To achieve the certified permissible error limit of ≤ 0.15% for hydrogen, sample preparation protocols require pulverizing analytical specimens to a mesh fineness of less than 0.2 mm. Utilizing an analytical microbalance, approximately 65 mg of conditioned specimen is weighed directly into a high-purity combustion boat. The micro-charge size not only preserves scarce or hazardous specimens but also minimizes reagent consumption within the internal purification trains.

During routine operation, the internal micro-printer automatically documents specimen sequence numbers, tare balances, gross burn weights, conversion durations, and final concentrations. This eliminates clerical transcription errors and reinforces laboratory data integrity across rigorous ISO 17025 accredited workflows.
