Overview
The INNUO DH900B Carbon Black Content Analyzer is a precision thermal gravimetric instrument engineered for the quantitative determination of carbon black content in polyolefin-based polymers—including polyethylene (PE), polypropylene (PP), and polybutene—using standardized pyrolytic decomposition under controlled inert and oxidative atmospheres. Based on the principle of thermogravimetric analysis (TGA) coupled with sequential nitrogen- and oxygen-purged thermal treatment, the DH900B implements the tube-furnace method as defined in ISO 6964 (equivalent to GB/T 13021–2023) and complementary standards such as GB/T 2951.41–2008 (IEC 60811-4-1) and JTG E50–2006 (Test Method T1165). The system performs automated, multi-stage thermal protocols—including blank crucible pre-burning, sample pyrolysis under N₂, and subsequent oxidation under O₂—to isolate volatile organic mass loss (attributable to polymer matrix) from residual inorganic ash (including carbon black and mineral fillers). This enables accurate, traceable calculation of carbon black concentration (wt%), ash residue, and filler content without manual gas switching or temperature reconfiguration.
Key Features
- 7-inch high-resolution capacitive touch interface displaying real-time furnace temperature, setpoint, thermal stage status (pyrolysis, oxidation, isothermal hold, blank tube burn-off), gas flow status (N₂/O₂), elapsed operation time, and ambient environment alerts.
- Integrated furnace-controller architecture minimizing footprint and simplifying laboratory integration; no external control cabinet required.
- Pre-programmed thermal profiles for pyrolysis, decomposition, and blank tube conditioning—stored internally and recalled via single-button activation for repeatable, operator-independent execution.
- Dual-gas auto-switching module with calibrated float-type flowmeters: 3 L/min range (0.1 L/min resolution) for wire & cable applications; 250 mL/min range (12.5 mL/min resolution) for pipe & fitting testing per GB/T 13021.
- Optional rapid cooling accessory enabling accelerated furnace cooldown between runs, improving throughput in high-volume QC environments.
- Double-latch rotary door design ensuring secure sealing during high-temperature operation while facilitating ergonomic sample loading/unloading.
- Nanofiber ceramic blanket insulation providing uniform axial and radial temperature distribution across the 370 mm heating zone (±2 °C typical uniformity at 600 °C).
Sample Compatibility & Compliance
The DH900B accommodates two standardized combustion boat geometries: (1) 93 mm total length (70 × 16 × 11 mm cavity) for wire/cable specimens per GB/T 2951.41; and (2) 72 mm total length (55 × 7 × 9 mm cavity) for pipe/tube granules per GB/T 13021. All thermal protocols comply with ASTM D1606 (historical reference), ISO 6964:2022, IEC 60811-4-1:2012, and JTG E50–2006 T1165. Instrument validation supports GLP-compliant documentation requirements, including audit-trail-capable parameter logging (optional with upgraded firmware), calibration certificate traceability to national metrology institutes, and full alignment with QA/QC workflows in rubber, plastic, and cable manufacturing facilities subject to ISO 9001 or IATF 16949 certification.
Software & Data Management
The embedded control firmware supports PID-based programmable temperature ramping with up to 10 user-defined segments, automatic memory retention of last-used parameters, and real-time deviation monitoring against setpoints. Mass input is entered manually via touchscreen keypad; the system computes carbon black content using the standard formula: CCB = [(m1 – m2) / m0] × 100%, where m0 = initial sample mass, m1 = mass after pyrolysis, and m2 = final ash mass post-oxidation. Results are output via built-in thermal printer (80 mm paper width); optional RS-232/USB interfaces enable export to LIMS or Excel-compatible CSV files. Firmware updates maintain compatibility with evolving regulatory reporting formats, including FDA 21 CFR Part 11–aligned electronic signature readiness (when paired with external authentication modules).
Applications
- Quality control of carbon black loading in PE/PP pipe extrusion compounds per ISO 4427 and ASTM F714 specifications.
- Verification of pigment dispersion consistency in automotive interior trim and under-hood components.
- Regulatory compliance testing for halogen-free flame-retardant (HFFR) cable sheathing materials.
- R&D screening of novel nanocomposite formulations containing conductive carbon black or hybrid filler systems.
- Third-party certification testing for CE-marked geosynthetic membranes (EN 13257) and landfill liner materials.
FAQ
What standards does the DH900B directly support?
It fully implements GB/T 13021–2023 (ISO 6964), GB/T 2951.41–2008 (IEC 60811-4-1), JB/T 4278.17–2011, and JTG E50–2006 T1165.
Can the instrument operate with mass flow controllers instead of float meters?
Yes—gas mass flow controllers (MFCs) are available as factory-installed options for enhanced repeatability and digital flow feedback.
Is the thermal printer mandatory?
No—it is integrated but may be disabled; data can be exported exclusively via USB or serial interface upon request.
What is the maximum operating temperature and stability specification?
The furnace achieves 999.9 °C with ±1 °C long-term stability at 600 °C (24 h dwell) under load, verified per ASTM E1142 calibration protocol.
Does the system include calibration tools or certificates?
Each unit ships with a NIST-traceable temperature calibration certificate; optional annual recalibration service packages are available through INNUO’s authorized service centers in APAC and EMEA.
