Overview
The CSBox-Tube Infrared Carbon-Sulfur Analyzer is a high-precision, dual-channel combustion-based elemental analyzer engineered for quantitative determination of total carbon (C) and sulfur (S) in solid inorganic and organic matrices. It operates on the principle of high-temperature combustion followed by non-dispersive infrared (NDIR) spectroscopy—complying with core methodologies referenced in ASTM E1019, ISO 15350, and USP . Samples (10–200 mg) are combusted in a programmable tubular or vertical furnace at temperatures up to 1550 °C, generating CO₂ and SO₂ gases. These gaseous products pass through integrated desiccant and particulate traps before entering dedicated NDIR measurement cells equipped with interference filters optimized for CO₂ (4.26 µm) and SO₂ (7.35 µm) absorption bands. Signal intensity is linearly correlated to concentration via calibrated reference curves, enabling direct mass-percent reporting of C and S with trace-level sensitivity and high reproducibility.
Key Features
- Configurable combustion architecture: selectable vertical-mode furnace (for refractory sulfides in ores, operating without O₂ carrier gas) and inclined tubular mode (optimized for volatile organics using quartz crucibles and Ni catalysts)
- Dual independent NDIR detection channels—each with temperature-stabilized detectors, pressure-regulated gas flow control, and real-time signal compensation for background drift
- Integrated Advantech single-board computer running FreeDOS, preloaded with proprietary firmware; supports password-protected HDD, audit-ready configuration logging, and GLP-compliant data archiving
- Modular hardware design: external Viton-sealed vacuum pump (Germany-sourced), compact combustion chamber volume (1/4–1/10 standard size) enhancing signal-to-noise ratio and detection sensitivity
- Eight user-selectable analysis protocols—including low-carbon mode, carbonate decarbonization (HCl pretreatment support), and standard calibration—enabling method-specific optimization per sample class
- Seamless balance integration: native protocol support for Sartorius, Mettler Toledo, Precia Molen, and Ohaus analytical balances; automatic weight capture and buffer storage for up to 90 sample IDs and masses
Sample Compatibility & Compliance
The CSBox-Tube accommodates heterogeneous solid samples including cement clinker, coal, coke, metallurgical ores, soils, agricultural feedstocks, biomass, petroleum coke, and geological specimens. Its vertical combustion mode eliminates reliance on oxygen as carrier gas for inorganic sulfide analysis—enabling field-deployable operation in mobile labs or remote sites under low-power conditions (≤1200 VAC). All operational parameters—including furnace ramp profiles, gas flow rates, and detector integration times—are configurable to meet ISO/IEC 17025 method validation requirements. The system supports full traceability per FDA 21 CFR Part 11 when paired with optional electronic signature modules and time-stamped audit logs.
Software & Data Management
Firmware is embedded on a hardened motherboard with no moving parts, ensuring long-term stability and minimal recalibration intervals. Data acquisition, peak integration, baseline correction, and stoichiometric conversion (C→CO₂, S→SO₂) occur in real time. Export formats include CSV, XML, and PDF reports compliant with LIMS interfaces. Raw spectra and calibration history are retained locally with timestamped metadata. Firmware updates are delivered via USB or LAN (RJ45); all minor patches and driver revisions are included in maintenance packages to reduce scheduled downtime. System diagnostics monitor combustion efficiency, gas purity, and detector health—triggering alerts prior to performance deviation.
Applications
- Quality control of raw materials in cement and steel production (e.g., limestone, blast furnace slag, ferroalloys)
- Environmental testing of soil and sediment for total sulfur content under EPA Method 9060A analog protocols
- Fuel characterization per ASTM D4294 (S in petroleum) and ASTM D5373 (C/S in coal and coke)
- Geochemical assay of sulfide minerals (pyrite, chalcopyrite) and carbonate-rich rocks
- Feed and fertilizer analysis for regulatory compliance with EU Regulation (EC) No 1069/2009
- R&D laboratories requiring flexible method development across organic/inorganic sample classes
FAQ
What sample types require vertical combustion mode?
Vertical mode is recommended for inorganic samples containing refractory sulfur species (e.g., metal sulfides in ores), where oxygen-free combustion prevents oxide interference and enables accurate S quantification without carrier gas dependency.
Is the instrument compliant with GMP/GLP documentation standards?
Yes—the system supports audit trails, user access controls, electronic signatures (optional), and immutable data logging aligned with ALCOA+ principles and Annex 11 requirements.
Can the CSBox-Tube analyze liquid or paste samples?
No—this model is designed exclusively for solid samples. Liquids require prior drying, ashing, or adsorption onto inert carriers (e.g., tungsten trioxide), which must be validated per method-specific SOPs.
What consumables are included in the SHV SPA kit?
The SHV SPA consumables pack contains 1000 analyses worth of ceramic crucibles, tin foil/sleeves, desiccant cartridges, filter elements, and IR cell cleaning tools—validated for consistent baseline stability over extended use.
Does the system support remote diagnostics or service access?
Yes—via secure LAN connection, authorized service engineers can initiate remote firmware checks, calibration verification, and error log retrieval while maintaining data isolation per ISO/IEC 27001 guidelines.
