The Sensi+ NG Analyzer is a compact, laser-based analyzer designed for continuous contaminant monitoring in natural gas, biogas, and biomethane streams. Using ABB’s Off-Axis Integrated Cavity Output Spectroscopy, or OA-ICOS™, the analyzer measures hydrogen sulfide, water, carbon dioxide, and oxygen from one platform.
This multi-contaminant design helps operators reduce analyzer complexity while maintaining fast access to critical gas quality data. Instead of installing separate instruments for each contaminant, Sensi+ NG brings four important measurements into one wall-mounted analyzer.
Natural gas contaminants can create safety, quality, compliance, and asset integrity concerns. Hydrogen sulfide can create serious safety risks and contribute to corrosion. Water can support hydrate formation, corrosion, and pipeline quality issues. Carbon dioxide can affect gas quality and may contribute to corrosion in certain operating conditions. Oxygen ingress can point to process issues and may increase corrosion risk in pipeline and storage systems.
By continuously measuring H₂S, H₂O, CO₂, and O₂, Sensi+ NG helps operators identify changes in gas quality before they become larger operational problems.
The Sensi+ NG Analyzer provides real-time measurement data to support quick decisions during process upsets. This is especially important in gas processing, pipeline transmission, custody transfer, and tariff compliance applications where contaminant levels must remain within acceptable limits.
The analyzer’s fast response and continuous monitoring capability help operators protect pipeline systems, storage facilities, and other mission-critical natural gas assets.
Sensi+ NG is also well suited for biogas upgrading and biomethane injection applications. Raw biogas often requires treatment to reduce hydrogen sulfide, carbon dioxide, and moisture before it can meet pipeline quality requirements. Oxygen monitoring also helps operators identify air ingress or process issues that may affect biomethane quality.
The analyzer’s compact footprint and low maintenance requirements make it a strong fit for remote or rural production sites where frequent technician visits may be difficult.
Sensi+ NG is designed to simplify long-term analyzer ownership. It requires no scrubbers, chemicals, liquids, tape, zero gas, carrier gas, UV light source, or nitrogen purge gas. This reduces operating costs, lowers maintenance demands, and simplifies consumable management.
Built-in diagnostics, Dynamic QR code reporting, AnalyzerExpert™ features, modular service components, and remote support tools help maintenance teams troubleshoot quickly and maintain analyzer performance over time.
By delivering accurate, real-time contaminant measurement, Sensi+ NG helps facilities protect assets, maintain compliance, and improve confidence in natural gas and biomethane quality.
