SS2100 gas analyzer

Field of application

Using patented tunable diode laser absorption spectroscopy (TDLAS) technology, the SS2100 gas analyzer measures specific gases (H₂O, CO₂, H₂S, NH₃, and C₂H₂) 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 & NH₃, ppm level measurement of H₂O, H₂S, CO₂, NH₃, and C₂H₂, 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, acetylene converter, caustic wash tower

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, NH₃, C₂H₂

• Measuring principle

  TDLAS

• Product Headline

  An advanced gas analyzer for hydrogen sulfide (H2S) measurement. The SS2100 uses tunable diode laser absorption spectroscopy (TDLAS) to determine the concentration of the analyte without coming into physical contact with the stream.
