Overview
The Sundys SDTGA6000V/6001V/6002V Coal and Carbon Industrial Analyzer is a fully automated, dual-zone thermogravimetric system engineered for precise, high-throughput volatile matter determination in solid fossil fuels and carbonaceous materials. Based on standardized loss-on-heating methodology under controlled inert or oxidative atmospheres, the instrument implements gravimetric mass-loss measurement following ISO 562:2010, ASTM D5142-2009, GB/T 212-2008, and GB/T 30732-2014 protocols. Its core architecture integrates two thermally isolated chambers—low-temperature weighing/cooling zone and high-temperature pyrolysis zone—enabling sequential sample conditioning, tare stabilization, and rapid thermal decomposition without manual intervention. Designed for routine QC/QA laboratories in coal preparation plants, coking facilities, carbon material producers, and waste fuel characterization centers, the analyzer delivers traceable, auditable results aligned with GLP and GMP documentation requirements.
Key Features
- Dual-chamber vertical configuration: Independent low-temperature (≤150 °C) weighing/cooling chamber and high-temperature (up to 1000 °C) furnace chamber enable concurrent sample handling and thermal analysis, minimizing cycle time per batch.
- Patented sample delivery mechanism: Precision-engineered robotic arm ensures stable, orientation-controlled insertion of crucibles into the furnace—eliminating sample tipping, sliding, or positional drift during transfer.
- User-configurable thermal profiles: Operators define sample mass range (0.5–10 g), pre-heating temperature, final pyrolysis temperature, dwell time, and cooling ramp parameters via intuitive interface.
- Integrated high-resolution microbalance: 0.0001 g readability balance with external LED display mounted at operator eye level enables real-time mass monitoring during taring and post-test residue evaluation.
- 26-position carousel: Accommodates 25 test samples plus one dedicated blank position for background correction and system validation prior to each run.
- Robust thermal insulation and PID-controlled heating elements ensure ±2 °C furnace stability across full operating range, critical for reproducible volatile release kinetics.
Sample Compatibility & Compliance
The SDTGA6000V/6002V variant is validated for coal, coke, solid biomass fuels, and solid/hazardous waste matrices per GB/T 212-2008 and ASTM D5142-2009. The SDTGA6001V variant extends compatibility to carbon industry feedstocks and intermediates—including needle coke, calcined petroleum coke, graphite electrodes, baked anodes, carbon paste, and graphitized products—per YB/T 5189, GB/T 3521, YS/T 587, and GB/T 2001. All models support method validation reports, audit trails, and electronic signature functionality compliant with FDA 21 CFR Part 11 when paired with optional LIMS integration modules. Instrument qualification documentation (IQ/OQ/PQ) templates are provided for laboratory accreditation under ISO/IEC 17025.
Software & Data Management
The embedded Windows-based control software provides full method development, sequence scheduling, real-time curve visualization (mass vs. time/temperature), and automatic calculation of volatile matter content as weight percent (dry basis or as-received basis). Raw data files (CSV, TXT) include timestamped metadata: operator ID, sample ID, crucible ID, ambient humidity/temperature, balance calibration status, and furnace thermocouple verification logs. Exported reports conform to ASTM-compliant formatting and include uncertainty estimation per GUM (Guide to the Expression of Uncertainty in Measurement). Optional network licensing supports multi-user access with role-based permissions (e.g., analyst, supervisor, QA reviewer) and centralized database archiving.
Applications
- Routine industrial analysis of raw coal blends prior to pulverization and combustion optimization.
- Quality surveillance of metallurgical coke in blast furnace operations.
- Volatility profiling of alternative solid fuels including torrefied biomass, RDF, and sewage sludge ash composites.
- Carbon material R&D: kinetic modeling of devolatilization behavior in needle coke precursors and anode-grade calcined coke.
- Regulatory compliance testing for EPA Method 28, EN 15403 (solid recovered fuels), and China’s GB 18597–2023 hazardous waste identification standards.
- Interlaboratory round-robin studies requiring inter-instrument comparability under ISO 5725-2 precision criteria.
