Rapid Automatic Hydrogen Analyzer Carbon and Hydrogen Determination System

Product Overview

This rapid automatic hydrogen analyzer is a high-precision analytical instrument engineered for the quantitative determination of carbon and hydrogen content in coal, coke, organic residues, and varied solid mineral materials. Replacing conventional, labor-intensive three-stage tube furnace combustion methods, this system integrates automated high-temperature thermal conversion, precise multi-stage temperature staging, and an advanced coulometric electrolytic titration cell into a unified, high-efficiency benchtop architecture. The equipment provides modern analytical facilities with rapid cycle times, digital data computation, and direct printer reporting, drastically reducing manual calculation errors while elevating laboratory throughput.

Designed primarily for testing laboratories in coal mining, thermal power generation, metallurgical processing, chemical manufacturing, and environmental analysis, the system excels in industrial quality inspection and research-grade characterization. By employing advanced microcomputer control, the unit automates thermal stage progression, gas flow coordination, integration of electrolysis current, and multi-point mathematical corrections. Whether utilized for standard calorific value corrections, boiler combustion efficiency calculations, or raw fuel procurement valuation, the equipment delivers analytical certainty across diverse sample matrices.

Engineered to maintain operational consistency under rigorous high-volume testing schedules, this instrument combines heavy-duty thermal insulation with stable electrolytic cell dynamics. High-grade heating elements and precision-wound sensing systems ensure that thermal targets remain exceptionally stable throughout continuous combustion runs. Analytical departments gain a dependable, low-maintenance workhorse capable of meeting exacting laboratory productivity targets while conforming rigorously to established industry testing norms.

Key Features

• Microcomputer-Controlled Analytical Automation: The system incorporates dedicated microprocessor automation that manages the complete combustion sequence, sensor polling, mathematical corrections, and digital readout, eliminating operator intervention and computational variability during standard testing runs.
• Dual-Mode Elemental Determination: While serving as a dedicated rapid coulometric analyzer for hydrogen content spanning from 0% to 20%, the system natively supports quantitative carbon analysis across 1% to 99% via the gravimetric absorption method in strict accordance with standard test criteria.
• Rapid Combustion and Testing Cycle: Completing a comprehensive analysis within 10 to 13 minutes per sample, the unit significantly outpaces legacy manual multi-stage combustion methods, allowing commercial testing laboratories to dramatically expand their daily sample turnaround.
• High-Precision Coulometric Electrolysis Detection: Featuring dual electrolysis operating voltages (10V coating electrolytic potential and 24V operating potential) paired with a high-current threshold exceeding 500 mA and a sharp cutoff below 60 mA, the titration cell delivers consistent detection fidelity across fluctuating sample moistures.
• Exceptional Coulometric Integrator Stability: The electronic integrator maintains a linearity tolerance of ±0.1%, ensuring that low-level and high-level hydrogen concentrations are quantified with uniform linearity, minimal drift, and certified baseline stability.
• Programmable Multi-Zone Thermal Profiling: Precision-engineered thermal controllers maintain the primary combustion zone at 800°C ± 10°C and secondary reaction staging at 300°C ± 10°C, utilizing pre-programmed dwell intervals (including designated holds at 300°C and 500°C) to secure complete combustion without sample decrepitation.
• Compact Integrated Construction: The equipment unites the combustion tube assembly, heating furnace, gas scrubbers, electrolytic cell, electronic power modules, and user interface into a single, cohesive chassis engineered for superior thermal insulation and rapid benchtop commissioning.
• Intuitive Tactile Interface and Direct Documentation: An integrated membrane keypad allows rapid sample parameter and tare entry, paired with direct digital display of hydrogen mass in milligrams, combustion-sample hydrogen weight percentage, and automatic report printing.

Why Choose This Product

• Superior Thermal and Mechanical Engineering: Unlike modular multi-unit setups that suffer from loose thermal coupling, heat loss, and delicate external tubing interconnects, this equipment features an integrated, high-efficiency monobloc structure. Premium thermal insulation surrounds the heating chambers, minimizing exterior chassis skin temperatures, shielding internal electronics, and reducing benchtop ambient heat load.
• Certified Analytical Compliance and Precision: Built to fulfill the stringent accuracy requirements of standard solid-fuel testing protocols such as GB476-91, the system delivers an analytical repeatability tolerance under 0.15% for hydrogen and under 0.50% for carbon within the same laboratory environment, giving technicians and auditing authorities unquestioned data validity.
• Robust Coulometric Electrolytic Cell Technology: The electrolytic titration core utilizes carefully calibrated dual-voltage rails—a 10V coating potential and a 24V active electrolytic drive—paired with high-current capability (>500 mA) to instantaneously capture and react moisture released from combustion. This avoids the moisture condensation bottlenecks and detector drift common in legacy instrumentation.
• Intelligent Microcomputer Data Processing: The onboard digital processing system automatically applies sample weight normalization, system blank deductions, and mathematical corrections to display absolute hydrogen mass as well as final dry-basis concentration percentages. Direct serial report printing generates permanent analytical records for laboratory information management.
• Dedicated Technical Support and Long-Term Reliability: Backed by specialized engineering expertise in high-temperature laboratory furnaces, analytical heating systems, and consumable components, every unit undergoes rigorous factory calibration and quality checks prior to dispatch, ensuring effortless installation, minimal downtime, and long service life.
