MAX-iAQ

Continuous Ambient Air Monitoring System for Low-Level Detection

The Thermo Scientific MAX-iAQ is a cutting-edge solution for ambient air quality monitoring that provides high sensitivity and reliability in detecting trace compounds, even in challenging environments with high humidity. Utilizing Fourier Transform Infrared (FTIR) technology, the MAX-iAQ system offers fast and accurate quantification of a wide range of compounds, including both organic and inorganic gases. Its advanced StarBoost Technology enhances its sensitivity, enabling the detection of compounds down to single-digit ppb levels, which makes it an ideal alternative to slower and more maintenance-intensive gas chromatography systems.

Engineered for continuous operation with minimal user interaction, the MAX-iAQ system can monitor up to 20 sample locations simultaneously, offering real-time data and dynamic alarming for seamless integration into existing workflows. The system’s temperature-controlled rack and integrated sample multiplexer ensure reliable sample flow across all channels. Whether deployed in industrial facilities, cleanrooms, or environmental monitoring applications, the MAX-iAQ is designed for long-term performance, requiring minimal maintenance over its 10+ year lifespan. It also features a user-friendly software suite for remote monitoring, sequencing, and data publishing.

Built to operate 24/7, the MAX-iAQ system offers easy setup with factory calibration, while allowing for additional calibration if needed. This robust system provides a complete, factory-ready solution for any ambient air monitoring need, supporting industries in ensuring environmental health and safety.
