For H2S the SS2100 Analyzer is capable of measuring hydrogen sulfide using tunable diode laser technology. The SS2100 delivers precise, reliable measurements and dramatically reduces maintenance costs.
This application measures H2S with typical measurements of 0-20 ppm with a repeatability of ± 500 ppb.
Application Code: 10902
Application Note
SpectraSensors SS2100 H2S Measurement Analyzer measures hydrogen sulfide in natural gas quickly and reliably without light source aging, tape replacement or ongoing recalibration.
The SS2100 H2S is perfect for remote or hazardous installations because its patented, laser based technology and requires very little annual maintenance. Factory set calibration last the full lifetime of the analyzer.
SpectraSensors analyzers are the first to offer truly dependable technology and simple operation for applications such as natural gas pipelines monitoring.
By its nature, the TDL (Tunable Diode Laser) detection method is not susceptible to aging effects. Excellent measurement repeatability between instruments compared to lab instruments makes the SS2100 H2S analyzer the ideal measurement tool for even the most punishing of environments.
Sensitive enough to meet the needs of critical tariff applications, the analyzer has operating ranges of 0-10 ppmv to percent levels and repeatability as low as ±500 ppbv.
The SS2100 H2S is remarkably easy to install; connect the power, the data link and the measured gas line and the analyzer begins working. Once set up, measurements begin within minutes.
The SS2100 H2S analyzer is available in many configurations. An optional measurement cell can be added to the analyzer for dual measurement H2S specifications, see the SS2000 product sheets.
