Beifen Sanpu HL-10A Intelligent Adsorption Tube Aging Instrument

Overview

The Beifen Sanpu HL-10A Intelligent Adsorption Tube Aging Instrument is a dedicated thermal conditioning system engineered for the precise and reproducible activation of sorbent-packed sampling tubes used in thermal desorption–gas chromatography (TD–GC) workflows. Designed as a critical pre-analytical component in volatile organic compound (VOC) and semi-volatile organic compound (SVOC) analysis, the HL-10A operates on resistive heating with PID-controlled temperature regulation to remove residual contaminants, moisture, and background volatiles from adsorbent beds—ensuring baseline stability, method robustness, and compliance with ISO 16000-6, EPA TO-17, and ASTM D6196 requirements. Its architecture integrates dual-zone thermal management (heating zone + cooling zone), programmable gas purging, and fail-safe thermal cutoff logic—making it suitable for routine QC laboratories, environmental monitoring agencies, and GLP-compliant testing facilities where trace-level accuracy and inter-batch consistency are mandatory.

Key Features

• 10-position parallel tube aging station with independent thermal zoning per rack position, enabling uniform heating across all 10 tubes (6 mm OD × ≥110 mm L or 1/4″ OD × ≥3.5″ L)
• 5-inch capacitive touch display interface with intuitive menu navigation, real-time parameter visualization (temperature, flow, time remaining), and password-protected method storage
• PID-based temperature control with ±1 °C accuracy over the full range (ambient to 400 °C); maximum setpoint limit configurable to prevent adsorbent degradation
• Integrated safety interlocks: automatic power cutoff upon exceeding user-defined upper temperature threshold (default 420 °C), overcurrent protection, and open-circuit heater detection
• Programmable gas purge sequence: inert gas (N₂ or He) flow adjustable from 0–1000 mL/min with digital mass flow control; post-aging auto-cooling protocol terminates gas flow once target cooldown temperature is reached
• Extended aging duration support: up to 999 hours per program cycle, accommodating rigorous conditioning protocols for Tenax TA, Carbopack B/C, graphitized carbon black, and multi-bed sorbents
• Optional simulated sampling module for controlled introduction of certified standard vapors directly into aged tubes—enabling calibration verification and breakthrough testing

Sample Compatibility & Compliance

The HL-10A accommodates standard 6 mm OD and 1/4″ OD adsorption tubes conforming to ASTM D6196 Annex A1 geometry specifications. It supports all common sorbent media—including polymer-based (Tenax GR, Tenax TA), carbonaceous (Carboxen 1000, Carbopack X), and composite beds—without requiring mechanical adaptation. The instrument meets electromagnetic compatibility (EMC) Class B per IEC 61326-1 and electrical safety standards IEC 61010-1. Its operational parameters align with EPA Method TO-17 section 6.2 (tube preconditioning), ISO 16000-6 Annex C (sorbent tube cleaning), and CNAS-CL01:2018 requirements for equipment qualification in accredited testing laboratories.

Software & Data Management

While the HL-10A operates via embedded firmware without external PC dependency, its onboard memory stores up to 20 user-defined methods with timestamped execution logs (start time, end time, peak temperature, average flow rate). All logs are exportable via USB flash drive in CSV format for audit trail generation. The system supports 21 CFR Part 11–compatible data integrity practices when paired with laboratory information management systems (LIMS) through optional RS-232 or Ethernet modules (sold separately). Audit trails include operator ID (via login), parameter changes, and alarm events—fulfilling GLP/GMP documentation requirements for regulated environments.

Applications

• Pre-conditioning of sorbent tubes prior to active/passive air sampling in indoor air quality (IAQ) and ambient air monitoring programs
• Regeneration of reused tubes in occupational hygiene surveys (e.g., NIOSH 5515, OSHA PV2120)
• Method validation studies requiring consistent tube blank characterization and breakthrough volume determination
• Calibration standard preparation via dynamic spiking using the optional simulated sampling accessory
• Quality assurance in third-party environmental labs accredited to ISO/IEC 17025:2017
• Routine maintenance of thermal desorption systems in university research labs and metrology institutes

FAQ

What tube dimensions does the HL-10A support?
Standard configurations include 6 mm outer diameter × ≥110 mm length and 1/4 inch (6.35 mm) OD × ≥3.5 inch (88.9 mm) length tubes. Custom fixtures are available upon request.
Is the gas flow rate calibrated and traceable to national standards?
Yes—the integrated mass flow controller is factory-calibrated against NIST-traceable standards; calibration certificates are provided with each unit.
Can the HL-10A be integrated into automated TD–GC workflows?
It operates as a standalone benchtop unit but features dry-contact I/O ports for external start/stop triggering and status signaling—enabling synchronization with autosamplers or LIMS event logging.
Does the instrument support IQ/OQ/PQ documentation packages?
Comprehensive qualification templates (including test protocols, acceptance criteria, and raw data worksheets) are supplied with purchase for installation qualification (IQ), operational qualification (OQ), and performance qualification (PQ) execution.
What maintenance is required for long-term reliability?
Annual verification of temperature uniformity (per ASTM E220) and flow accuracy is recommended; no consumables other than standard-grade inert gas are required during normal operation.
