The BC Index

The BC Index, a proprietary metric, assesses air quality, particularly Black Carbon levels, aiding organizations in monitoring and communicating pollution. Additionally, it offers real-time tracking, assisting individuals in informed decisions about outdoor activities, and supporting WHO 2021 guidelines. Lastly, the AE36 instrument adjusts the BC Index to suit specific concentration ranges in different areas

Autonomous self-cleaning for enhanced accuracy

Designed for extended unattended operation, features a self-cleaning procedure that reduces maintenance and ensures accuracy. Its proprietary technology cleans the optical chamber and internal tubing periodically, preventing dirt buildup that could impact data quality. With 2-times longer filter tape, the AE36 minimizes site visits while maintaining high-quality data. Additionally, it remains robust in varying environments, including changes in relative humidity caused by air conditioning.

Real-time source apportionment

It examines samples across 7 optical wavelengths (370 nm to 950 nm), distinguishing variations in aerosol components like diesel exhaust and biomass burning emissions. This data separation allows for real-time identification of aerosol sources and origins. Its source apportionment algorithm, utilizing filter loading compensated data (DualSpot), guarantees precise and instant source categorization

Easy to use, robust performance

Designed to offer valuable insights with minimal resource needs, featuring a user-friendly interface for easy navigation. Real-time data visualization enables users to swiftly grasp key information from the previous week. Additionally, a new status control feature automatically validates data, ensuring accuracy for dependable analysis and reporting.

Patented automatic compensation for filter loading effect

It tackles the filter loading effect during sample collection and analysis by simultaneously analyzing two filter spots at different flow rates. Mathematically combining the data eradicates the filter loading effect, delivering continuously corrected real-time data without interruptions as the filter progresses. This compensation method, reliant on aerosol composition and properties, must be determined in real time from measurement data. The parameters derived from this analysis also provide additional insights into aerosol composition and aging, enhancing overall data comprehension

Data Validation

Data validation is crucial for maintaining quality assurance and control (QA/QC). Automated data validation eliminates the necessity for manual validation, saving time and reducing the risk of human error. Implementing new status controls for automatic data validation establishes a solid foundation for dependable and precise data analysis and reporting.
