Microcomputer Multi Sample Sulfur Analyzer for Coal Coke and Petroleum

Product Overview

This high-throughput sulfur determination system delivers automated, high-precision quantitative analysis of total sulfur content in combustible materials, including raw coal, metallurgical coke, petroleum fractions, and alternative solid fuels. Utilizing advanced coulometric titration coupled with automated sample sequencing, the equipment integrates dual-stage high-temperature combustion with continuous microcomputer analysis. It streamlines laboratory testing routines by replacing slow manual methods with rapid, unattended sample processing and automated error calibration.

Engineered specifically for heavy-demand industrial laboratories, commercial inspection bodies, thermal power plants, and petrochemical refineries, the system processes up to twenty distinct samples per analytical sequence while supporting continuous sample loading. The automated multi-sample feeder ensures reliable sample transition between heating phases, eliminating mechanical bottlenecks and minimizing human intervention during peak testing cycles.

Built for rigorous continuous operation, the unit incorporates heavy-duty silicon carbide heating elements, robust platinum electrolytic assemblies, and integrated electrical protection systems. Its rugged architecture ensures thermal stability at continuous high temperatures, safeguarding sensitive electrochemical detection cells and providing uncompromised analytical precision across long operating shifts.

Detail & Parts

Key Features

• Automated Twenty-Sample Carousel with Continuous Loading: The integrated sample handler accommodates up to twenty samples in a single sequence and permits continuous sample introduction at any time during an active run, maximizing laboratory throughput and eliminating batch-reset downtime.
• Precision Microcomputer Control and Automated Calibration: The onboard processing system automates the entire analytical workflow, from sample entry and boat positioning to electrolytic endpoint detection, data logging, and algorithmic error correction for consistent inter-sample reliability.
• Programmed Dual-Stage Combustion Kinetics: Thermal processing follows an automated profile with a 45-second pre-pyrolysis dwell at 500°C followed by a 4-minute 45-second combustion dwell at 1050°C, ensuring complete oxidation of complex sulfur compounds without premature volatilization.
• Silicon Carbide High-Temperature Heating Chamber: Engineered with a specialized silicon carbide resistance tube featuring a high-temperature zone length of at least 90 mm, the furnace delivers rapid thermal ramp-up rates of 20°C to 25°C per minute to reach operating conditions in approximately 30 minutes.
• High-Precision Coulometric Titration Cell: Equipped with a 450 mL reaction vessel and a 150 mm² high-purity platinum electrolytic electrode array, the cell delivers instantaneous titration of sulfur dioxide, achieving exceptional analytical repeatability and sensitivity.
• Intelligent Thermal Regulation and Protection Interlocks: An integrated PID temperature regulation platform maintains furnace stability within ±5°C while integrated safety interlocks provide automatic silicon carbide tube startup protection and overcurrent safeguards against line fluctuations.
• Comprehensive Historical Data Management: The integrated system architecture stores complete historical analysis datasets, enabling immediate retrieval, multi-parameter statistical filtering, and direct report generation via external printing interfaces.
• Automatic Thermal Compensation: Dynamic ambient temperature compensation algorithms continuously correct for baseline thermal drift, maintaining system measurement fidelity even in ambient test environments subject to room temperature shifts.
