Huiron HRH-SSM810 Fully Automated 10-Channel Linear Cigarette Smoking Machine

Overview

The Huiron HRH-SSM810 is a fully automated, linear-configured cigarette smoking machine engineered for high-reproducibility smoke generation in regulatory toxicology, clinical respiratory research, and tobacco product analysis. It implements standardized pneumatic actuation and synchronized mechanical handling to execute precise, repeatable puff sequences across ten independent channels—each driven by a dedicated, calibrated peristaltic or diaphragm-based smoking pump. The system operates on the principle of controlled negative-pressure aspiration, where programmable airflow profiles replicate human inhalation dynamics under ISO 308 (determination of total particulate matter) and ISO 4387 (determination of nicotine and water in cigarette smoke condensate). Its linear architecture enables unidirectional cigarette transport—from automated feed and ignition through combustion monitoring, butt ejection, and post-puff extinction—minimizing cross-channel interference and ensuring metrological traceability per channel. Designed specifically for laboratory environments requiring GLP-aligned experimental rigor, the HRH-SSM810 bridges analytical chemistry and inhalation toxicology workflows without manual intervention during routine operation.

Key Features

• 10 independently controlled smoking channels with isolated vacuum circuits, enabling parallel multi-sample exposure or inter-channel method comparison.
• Automated cigarette handling sequence: robotic magazine feeding, optical alignment verification, spark-ignition initiation, real-time burn-length monitoring via infrared sensor array, and mechanically triggered butt ejection upon pre-set criteria.
• Programmable puff parameters: volume (20–70 mL), interval (30 s or 60 s default, adjustable), duration (standardized 2-s draw time), and waveform profile—including ISO-compliant bell-shaped aspiration or user-defined custom curves for mechanistic inhalation modeling.
• Dual operational paradigms: Toxicological Exposure Mode (optimized for whole-body or nose-only rodent exposure chambers, with continuous puff synchronization and environmental stability logging) and Analytical Mode (designed for Cambridge filter pad collection, trap assembly compatibility, and gravimetric/chemical quantification per ISO protocols).
• Integrated safety subsystems: flame-out detection, overheat cutoff, emergency stop with hardware-latched relay, and smoke exhaust interlock to maintain fume hood or dedicated ventilation compliance.

Sample Compatibility & Compliance

The HRH-SSM810 accommodates standard commercial and research-grade cigarettes (including king-size, slim, and ventilated variants) with diameter tolerance of 7.5–8.5 mm and length range of 84–100 mm. Its mechanical gripper and conveyor design support both filtered and non-filtered rods without adapter modification. All pneumatic and thermal components are constructed from USP Class VI-certified polymers and 316 stainless steel to prevent analyte adsorption or leaching. The instrument meets the mechanical and procedural requirements of ISO 308:2020 and ISO 4387:2020 for total particulate matter (TPM), nicotine, and water determination. Optional audit trail modules enable 21 CFR Part 11–compliant electronic records when paired with validated LIMS integration. Calibration certificates traceable to NIM (National Institute of Metrology, China) are provided with each unit shipment.

Software & Data Management

The embedded control interface runs on a real-time Linux OS with deterministic I/O scheduling. The proprietary Huiron Smokelog™ software provides role-based access control (administrator, technician, auditor), full parameter logging (puff-by-puff pressure, flow rate, temperature, and timing), and export in CSV, XML, and ASTM E1461-compliant formats. Audit trails record all user actions—including method changes, calibration events, and error acknowledgments—with immutable timestamps and operator ID binding. Data integrity safeguards include automatic checksum validation, write-once storage partitioning, and optional encrypted network transmission to central servers. Remote diagnostics and firmware updates are supported via TLS-secured Ethernet connection, with no cloud dependency required for core operation.

Applications

• Toxicological inhalation studies: generating reproducible mainstream smoke for acute/chronic exposure in OECD 412, 413, and 429-compliant rodent models.
• Clinical respiratory research: simulating patient-specific puff topography in hospital-based COPD or asthma biomarker discovery pipelines.
• Tobacco product assessment: comparative TPM, CO, and carbonyl compound profiling across conventional, heated tobacco, and novel nicotine delivery systems.
• Regulatory submission support: generating GLP-auditable datasets for PMTA (FDA), TPD (EU), or MHRA dossier preparation.
• Method development labs: validating alternative smoking regimens (e.g., intense puffing, reduced ventilation) for harm reduction evaluation.

FAQ

Does the HRH-SSM810 support non-standard puff protocols beyond ISO 308?

Yes—users may define custom puff volumes, intervals, durations, and waveforms via the Smokelog™ editor; all profiles are stored with version-controlled metadata.

Is the system compatible with third-party exposure chambers?

All 10 channels feature standardized 6-mm OD silicone tubing outlets and vacuum-rated quick-connect fittings, enabling direct integration with common whole-body/nose-only chambers (e.g., CH Technologies, Promech Lab).

How is calibration verified and maintained?

Each channel includes integrated flow sensors (±1.5% FS accuracy) and pressure transducers (±0.5% FS); annual recalibration is performed using NIST-traceable dry calibrators and documented per ISO/IEC 17025.

Can the system operate unattended for extended sessions?

With a full 200-stick magazine load and scheduled maintenance cycles, the HRH-SSM810 supports up to 72 hours of continuous operation under monitored laboratory conditions.

What documentation is supplied for regulatory audits?

Deliverables include Factory Acceptance Test (FAT) report, Installation Qualification (IQ), Operational Qualification (OQ), calibration certificates, software validation summary, and electronic audit trail configuration guide.
