Overview
The ANKO FLA 2.1 Gas Explosivity Limit Analyzer is a precision-engineered laboratory instrument designed for the experimental determination of flammability limits—specifically the Lower Flammability Limit (LFL) and Upper Flammability Limit (UFL)—of gaseous and vapor-phase chemical substances. Based on the standardized closed-vessel ignition method, the FLA 2.1 operates in strict accordance with ASTM E681, “Standard Test Method for Determination of Flammability Limits of Chemicals at Elevated Temperature and Pressure,” ensuring regulatory traceability and interlaboratory reproducibility. The system utilizes controlled spark ignition within thermally stabilized glass test vessels under precisely regulated atmospheric conditions, enabling quantitative assessment of the minimum and maximum fuel–air concentration thresholds at which sustained flame propagation occurs. Its robust thermal architecture—including a 50 L insulated heating chamber with PID-controlled temperature regulation (20–300 °C)—supports both ambient and elevated-temperature flammability testing, critical for evaluating process safety margins in chemical manufacturing, petrochemical refining, and pharmaceutical solvent handling.
Key Features
- Compliance with ASTM E681 for standardized flammability limit determination under controlled temperature and pressure conditions
- Dual-volume test vessel configuration: interchangeable 5 L and 12 L borosilicate glass explosion chambers, certified for repeated high-energy ignition cycles
- Integrated 50 L heating chamber with digital PID temperature controller, ±0.5 °C stability over full operating range (20–300 °C)
- High-voltage spark ignition system with adjustable energy output and synchronized optical flame detection
- Gas mixing manifold with mass flow controllers (MFCs) for precise stoichiometric blending of fuel, air, and inert diluents (e.g., N₂, CO₂)
- Explosion-resistant chamber enclosure with pressure-relief venting and real-time pressure monitoring (0–20 bar range)
- CE-marked electrical architecture compliant with IEC 61000-6-4 (EMC) and IEC 61000-6-2 (immunity) standards
Sample Compatibility & Compliance
The FLA 2.1 accommodates a broad spectrum of volatile organic compounds (VOCs), hydrocarbon gases (e.g., methane, propane, ethylene), hydrogen-containing mixtures, and halogenated solvents—provided they remain stable below 300 °C and do not chemically attack borosilicate glass or stainless-steel wetted components. It supports testing of binary, ternary, and multi-component gas mixtures, including those containing inert diluents used to simulate process off-gas or purge atmospheres. All operational protocols align with internationally recognized process safety frameworks, including CCPS (Center for Chemical Process Safety) guidelines and NFPA 497. Data generated meets documentation requirements for HAZOP studies, Layer of Protection Analysis (LOPA), and safety data sheet (SDS) Section 9 updates. The system is suitable for GLP-compliant laboratories when operated with validated SOPs and audit-trail-enabled software logging.
Software & Data Management
The FLA 2.1 is operated via ANKO’s proprietary Windows-based control software, which provides real-time visualization of temperature, pressure, gas composition, ignition timing, and flame propagation status. Each test sequence generates a timestamped, digitally signed report conforming to ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available). Audit trails record all user actions, parameter changes, and calibration events. Optional 21 CFR Part 11 compliance packages include electronic signatures, role-based access control, and encrypted database storage. Export formats include CSV, PDF/A-2, and XML for integration into LIMS or enterprise risk management platforms.
Applications
- Determination of LFL/UFL values for new chemical entities during REACH registration or TSCA pre-manufacture notification
- Validation of inerting strategies in reactor purging, distillation column blanketing, and powder handling systems
- Thermal sensitivity profiling of solvent blends used in coating, adhesive, and cleaning formulations
- Supporting QRA (Quantitative Risk Assessment) inputs for offshore platform design and refinery turnaround planning
- Academic research on flame inhibition mechanisms, kinetic modeling of premixed combustion, and pressure-dependent flammability behavior
FAQ
Does the FLA 2.1 support testing at pressures above atmospheric?
Yes—the system can be configured with optional pressure-rated test vessels and a pneumatic pressure control module to conduct tests up to 5 bar(g), per ASTM E681 Annex A4.
Can the instrument be used for dust cloud explosivity testing?
No—the FLA 2.1 is specifically engineered for gaseous and vapor-phase systems; dust explosivity requires a separate apparatus such as a 20 L sphere or Hartmann tube per ASTM E1226.
Is calibration traceable to national standards?
Temperature sensors are calibrated against NIST-traceable RTDs; pressure transducers are certified to ISO/IEC 17025 by an accredited third-party lab.
What maintenance intervals are recommended?
Quarterly verification of spark gap alignment and MFC accuracy; annual full system performance qualification including thermal uniformity mapping of the 50 L chamber.
Are spare test vessels and ignition electrodes available?
Yes—ANKO supplies certified replacement 5 L and 12 L glass vessels, tungsten-alloy electrodes, and quartz viewport assemblies with documented lot traceability.
