OA-ICOS Gas Analyzers for High-Precision Laser-Based Gas Measurement

ABB’s OA-ICOS Analyzer platform uses advanced off-axis integrated cavity output spectroscopy (OA-ICOS) to measure gas concentrations with precision, speed, and durability. For full product specifications, refer to the ABB OA-ICOS analyzer page. Building on the Los Gatos Research legacy, this fourth-generation laser spectroscopy method offers high sensitivity and ease of use compared to traditional techniques.

Advanced Laser Spectroscopy for Accurate Gas Analysis

These OA-ICOS analyzers use high-performance diode lasers and robust optical cavities to deliver real-time, drift-free measurements with minimal calibration. Their ability to measure trace gases at ultra-low concentrations makes them ideal for applications such as emissions monitoring, hydrogen purity, CO₂ measurement, and environmental compliance.

For applications requiring complementary multi-component gas analysis, systems such as the AO2000 Continuous Gas Analyzer System can be used alongside OA-ICOS analyzers to expand overall measurement capability.

Flexible Deployment Across Industrial and Laboratory Environments

OA-ICOS analyzers are available in portable, rackmount, benchtop, and wall-mounted configurations, making them adaptable to a wide range of installations. Their rugged design supports deployment in field monitoring stations, manufacturing plants, and cleanroom laboratories.

For simpler or cost-sensitive monitoring applications, the EasyLine Gas Analyzers provide an alternative solution for standard gas analysis requirements.

Real-Time Monitoring for Process Control and Compliance

With rapid data acquisition and long-term stability, OA-ICOS analyzers support continuous monitoring in applications such as carbon capture, air quality compliance, and industrial process optimization. Integrated software enables automated data collection, remote diagnostics, and seamless communication with plant control systems.

Low-Maintenance and Long-Term Reliability

These analyzers are designed for long-term, unattended operation with minimal consumables and reduced maintenance requirements. Their robust construction and stable measurement technology ensure reliable performance even in harsh environments.

By delivering accurate, real-time gas analysis, OA-ICOS analyzers help facilities improve safety, maintain compliance, and optimize process efficiency.
