Product Overview
This system is an advanced benchtop elemental analysis instrument engineered for automated, high-throughput quantitative sulfur determination in solid and liquid combustible samples. Built upon precision coulometric titration principles and high-temperature catalytic combustion pyrolysis, this equipment delivers analytical consistency, rapid sample cycling, and broad measurement dynamic ranges up to 99.99% total sulfur content.
Primarily deployed across coal mining operations, thermal power generation plants, metallurgy facilities, commercial coking plants, and petrochemical testing laboratories, the unit adheres strictly to standardized test protocols such as GB/T 214-2007. Its integrated multi-sample automation enables laboratories to eliminate repetitive manual sample handling, streamline testing workflows, and ensure dependable data integrity for environmental compliance, quality assurance, and combustion efficiency audits.
Engineered to endure continuous, round-the-clock industrial laboratory operation, this analyzer incorporates an advanced horizontal pyrolysis furnace paired with next-generation high-efficiency thermal insulation. Coupled with an intelligent high-speed ARM embedded processor and robust noise-rejection electronics, the equipment guarantees stable baseline drift, exceptional thermal accuracy, and repeatable analytical results even under demanding multi-shift testing environments.
Detail & Parts
Key Features
- High-Capacity 24-Position Carousel with Priority Queuing: The integrated continuous autosampler accommodates up to 24 samples in a single loading cycle, enabling fully unattended sequential determination. The intelligent sequencing software permits immediate insertion of urgent priority samples without interrupting active test routines or requiring system restarts, dynamically reorganizing combustion queues on the fly.
- Horizontal High-Temperature Pyrolysis Tube Furnace: Built with a specialized horizontal cracking chamber, this system achieves rapid thermal ramp-up and uniform heat distribution up to 1150°C for coal and solid fuels and 920°C for oils. Advanced low-thermal-mass insulating materials minimize radiant heat loss, cut energy consumption, and maintain an ultra-tight ±1°C operating temperature tolerance across prolonged operational shifts.
- Coulometric Titration Detection with Sub-ppm Resolution: Utilizing an advanced electrochemical cell and dynamic micro-coulometric integration, the analyzer measures total sulfur content spanning from 0% to 99.99% with an analytical resolution of 0.00001%. Continuous electrochemical titration delivers instant endpoint detection without requiring pre-standardized chemical titrants or tedious recurring calibration curves.
- Integrated Modular Architecture and Field-Interchangeable Feeder: The equipment houses the combustion furnace, electrolytic titration assembly, magnetic stirring cell, gas flow regulator, and multi-stage air purification system within a single space-efficient enclosure. The automatic mechanical sample feeder is engineered as an independent, batch-interchangeable assembly, simplifying routine bench servicing and maximizing operational uptime.
- Direct Electronic Balance Integration: Featuring a dedicated external electronic balance data interface, the system directly acquires specimen weights between 10 mg and 100 mg via a single balance keystroke. This automated data transfer eliminates manual transcription errors, automatically calculates specimen mass, and accelerates analytical throughput.
- High-Performance 32-Bit ARM Processing Core: Driven by an industrial-grade ARM microcontroller executing a real-time multitasking operating system, the system orchestrates temperature management, carrier gas delivery, electrolysis current integration, and position detection with sub-millisecond responsiveness and superior electromagnetic interference shielding.
- Multi-Device USB Communication Architecture: The digital communication subsystem utilizes hot-swappable industrial USB connectivity, allowing a single PC workstation to supervise, configure, and operate multiple sulfur analysis units concurrently, significantly multiplying testing capacity in high-volume commercial inspection centers.
- Self-Contained Gas Purification and Desiccation Train: An integrated carrier gas purification train thoroughly scrubs and desiccates incoming ambient air, ensuring consistent oxygen carrier flow free from moisture, acid vapors, and particulate contaminants to maintain optimal electrolyte longevity and peak measurement repeatability.
