    Optimising Particle Measurement Efficiency: The Essential Guide to the AVL Butanol Remover for Benelux clients.
    AAVOS International bv, Roger van Uden

    In the high-stakes world of ambient air monitoring and automotive testing, precision is everything. For researchers and lab managers across the Benelux region, Condensation Particle Counters (CPCs) are indispensable tools for measuring ultrafine particles. However, these instruments often rely on butanol as a working fluid, which can introduce a significant challenge: the release of butanol vapours into the laboratory or monitoring station environment.

    Without proper management, these exhaust emissions can lead to unpleasant odours, safety concerns, and—critically—interference with other sensitive measurements. This is where the AVL Butanol Remover becomes a vital component of your measurement chain.

    The Challenge: CPC Contamination and VOC Interference

    Ultrafine particles (typically below 100 nanometers) are a major focus of modern health and environmental regulations, including the latest EU Regulation 2024/2881 and WHO Air Quality Guidelines. To detect these particles, CPCs grow them using a vaporised working fluid—most commonly butanol—to a size that can be optically detected.

    The byproduct of this process is an exhaust stream saturated with butanol vapour. For multi-pollutant monitoring stations, this presents a severe technical hurdle: butanol is a Volatile Organic Compound (VOC), and its presence in the exhaust can significantly distort VOC measurement data, leading to inconsistent and non-comparable results.

    The Solution: The AVL Butanol Remover

    The AVL Butanol Remover is a specialized, low-maintenance solution designed to eliminate butanol vapour directly from the CPC exhaust stream. By integrating this device, labs can ensure a clean, safe, and interference-free operating environment.

    How It Works: Heated Catalytic Conversion

    The device utilizes heated catalytic conversion to process the exhaust. This advanced method achieves a removal efficiency of ≥ 99.9%, effectively converting butanol into clean air.

    Key Technical Features:

    • Automatic Temperature Control: Ensures stable operation and optimal conversion efficiency without manual intervention.


    • No Consumables: Unlike charcoal filters that require frequent replacement, the catalytic process requires no consumables, reducing long-term operational costs.


    • High Flow Compatibility: Designed to work with CPCs with flow rates up to 1 Nl/min, making it compatible with all standard commercial models.


    Key Benefits for Benelux Clients

    As the exclusive AVL partner for high-precision particle measurement in Belgium, the Netherlands, and Luxembourg, AAVOS International understands the specific needs of regional authorities and private labs.

    1. Reduced Downtime and Low Maintenance

    In continuous monitoring setups, equipment reliability is paramount. The AVL Butanol Remover is built for continuous operation, featuring automatic reboot capabilities and a robust design that minimizes the need for routine maintenance.

    2. Regulatory Compliance and Data Integrity

    With the Flanders Environment Agency (VMM) already deploying these integrated solutions in Belgium, the AVL Butanol Remover is a proven choice for maintaining ACTRIS-compatible ultrafine particle measurements. It ensures your station meets the rigorous EN 16976 standards for ambient air sampling by preventing cross-contamination between instruments.

    3. Cost-Effectiveness

    By extending the lifespan of co-located VOC sensors and eliminating the need for expensive filter consumables, the AVL Butanol Remover offers a rapid return on investment for high-precision labs.

    Technical Compatibility

    The AVL Butanol Remover is part of a modular, future-proof monitoring solution. While it is the perfect companion for the AVL UltraFine Particle Monitor™, its universal design ensures it is compatible with all commercial CPCs. Whether you are upgrading an existing air quality network or building a new automotive testing cell, this device integrates seamlessly into your infrastructure.
