Field of application

Using patented tunable diode laser absorption spectroscopy (TDLAS) technology, the SS2100 gas analyzer measures specific gases (H₂O, CO₂, and H₂S) with precision while avoiding interferences that are common with traditional infrared analyzers. The SS2100 analyzer requires little maintenance and does not need recalibration or periodic replacement parts.

Gas analysis: ppb level measurement of H₂O, ppm level measurement of H₂O, H₂S, and CO₂, and percent (%) level measurement of H₂S and CO₂

Natural gas: production, storage, transportation, distribution

Refinery: hydrogen recycle, catalytic reforming, flaring, cracking

Gas processing: fractionation, sour/acid gas removal

LNG: liquefication, custody transfer

Petrochemical: cracking, caustic wash tower

CCUS: measure trace H₂S and H₂O in 100% CO₂

Benefits

Accurate, real-time measurements
Low cost of ownership, no consumables and virtually maintenance-free and reliable in harsh environments
Available to measure up to 3 analytes in one unit (2-packs or 3-packs)
Provides measurements not hampered by wet-up (absorption) or dry-down (desorption)
Dependable with greater repeatability than surface-based sensors
Analog and serial outputs for remote monitoring
Available for following measurements: H₂O, CO₂, H₂S
