Overview
The Jing Mini CAST Carbon Black Aerosol Generator is a precision-engineered combustion-based aerosol source designed for laboratory-scale generation of authentic, engine-relevant carbon black nanoparticles. Unlike atomization or nebulization systems, the Mini CAST employs controlled hydrocarbon combustion—using either diffusion or premixed flame configurations—to produce carbonaceous particulate matter that closely replicates the morphology, surface chemistry, and size distribution characteristics of real-world diesel and gasoline engine exhaust soot. This physical fidelity makes it an essential tool in fundamental aerosol science, emission measurement validation, and filtration system development. The device operates on standard liquid hydrocarbon fuels (e.g., propane, butane, or certified test fuels), with flame geometry and air/fuel ratios precisely regulated to tune particle nucleation, coagulation, and growth dynamics in situ. Its compact footprint and modular design enable seamless integration into climate chambers, wind tunnels, and instrument calibration benches compliant with ISO 16000-8, ASTM D6245, and EU 2017/1151 RDE testing frameworks.
Key Features
- Combustion-derived carbon black aerosol with primary particle diameters spanning 10–200 nm—validated via SMPS and TEM analysis
- Dual-flame architecture: selectable diffusion flame (for higher mass output and agglomerated structures) or premixed flame (for narrower size distribution and lower volatile organic fraction)
- Mass output tunability from sub-milligram/hour to multi-gram/hour ranges, enabling scalable exposure studies and instrument challenge testing
- Integrated fuel flow control, thermocouple-monitored combustion zone, and back-pressure-regulated exhaust path for stable, repeatable aerosol generation
- PC-based automation software supporting scheduled operation, parameter logging (fuel pressure, flame temperature, dilution ratio), and remote start/stop via Ethernet or USB
- Compliant with ISO 27891:2019 for aerosol generator performance verification and traceable to NIST-traceable reference instruments
Sample Compatibility & Compliance
The Mini CAST delivers aerosols compatible with a broad range of downstream analytical and functional test platforms—including condensation particle counters (CPCs), optical particle sizers (OPS), photoacoustic soot spectrometers (PASS), and laser-induced incandescence (LII) systems. Its output meets the material and morphological requirements specified in PMP (Particle Measurement Programme) Phase 2 protocols for light-duty vehicle particulate number (PN) measurement system calibration. It supports GLP-compliant validation of smoke meters (ISO 11614), black carbon monitors (EN 16913), and real-time soot sensors used in aftertreatment R&D. All wetted components are constructed from high-purity stainless steel and ceramic, ensuring chemical inertness and minimizing catalytic oxidation artifacts during extended operation.
Software & Data Management
The proprietary CAST Control Suite runs on Windows OS and provides full bidirectional communication with the generator’s embedded microcontroller. Users define flame mode, fuel flow setpoints, dilution air ratios, and operational duration through an intuitive GUI. Real-time telemetry—including combustion chamber temperature, fuel line pressure, and status flags—is logged at 1 Hz resolution and exported in CSV or HDF5 format. Audit trails record all parameter changes with user ID, timestamp, and IP address—supporting FDA 21 CFR Part 11 compliance when deployed in regulated QA/QC environments. Optional API integration enables synchronization with third-party data acquisition systems (e.g., LabVIEW, Python-based DAQ frameworks) for closed-loop experimental control.
Applications
- Calibration and performance verification of regulatory-grade PN counters (e.g., TSI 3776, Cambustion DMS500)
- Functional testing of diesel particulate filters (DPF), gasoline particulate filters (GPF), and wall-flow substrate materials under realistic soot loading conditions
- Development and sensitivity assessment of optical smoke meters, laser scattering sensors, and photoacoustic black carbon detectors
- Fundamental studies of nanoparticle coagulation kinetics, surface oxidation behavior, and thermophoretic deposition mechanisms
- Generation of standardized challenge aerosols for fire detection system certification per UL 268 and EN 54-7
FAQ
What fuel types are compatible with the Mini CAST?
Propane, butane, and certified low-sulfur diesel surrogates are validated; fuel selection directly influences particle size distribution and volatile fraction.
Can the Mini CAST generate aerosol without dilution air?
Yes—though undiluted output exceeds safe handling limits for most instruments; integrated dilution modules (1:10 to 1:1000) are recommended for metrological applications.
Is the particle size distribution stable over time?
With proper warm-up (≥15 min) and constant environmental conditions, geometric standard deviation (σg) remains ≤1.25 over 4-hour continuous operation.
Does the system support automated sequence programming?
Yes—the CAST Control Suite allows creation of multi-step protocols including ramped fuel flow, timed flame mode switching, and synchronized data capture triggers.
How is traceability ensured for calibration use?
Each unit ships with a factory calibration report referencing NIST-traceable CPC and DMA standards; annual recalibration services include aerosol number concentration and size distribution verification.
