Analyzer for measuring H2S, H2O & CO2 – TISOMIC


The TISOMIC, with unique PA-TDL technology, is a proven and low maintenance on-line process analyzer for H2S, H2O, and CO2 with state of the art electronics. Typical applications of the TISOMIC include everything from H2S in multiphase crude oil, down to H2S, H2O and CO2 in sales gas and pipeline monitoring.

Key Benefits

  • Close to zero maintenance
  • No moving parts
  • Stable and simple calibration
  • Full separation of photo acoustic measuring cell and electronics
  • Detection range from low ppm to percentage levels
  • No limitations in natural gas matrix
  • Simultaneous multi-stream measurement of H2S, H2O and CO2 possible.
  • Analyzer cell flow of ±200 sccm/min

PA- TDL Technology

The TISOMIC with PA-TDL technology, Measuring the Photo Acoustic effect excited by a Tunable Diode Laser (TDL), can simultaneously measure H2S, H2O, and COin liquid and gas streams. Our PA-TDL technology consists of a high-quality microphone for detecting the Photo Acoustic resonance created by a tunable diode laser in the measuring cell. Analyzing in the low ppm range is achievable by using a resonator with a 10 centimeter path length, without the use of moving parts and multi-pass mirrors.

The product features include:

  • Low, less-than-200cc/min cell flow
  • Wide range over four decades (log scale)
  • Temperature controlled cell
  • Full separation of sample-wetted parts and electronics by using fiber optics

When the TISOMIC is used with a well-designed sample conditioning system, such as the Hobré HIFISC, it can run with a drift of typically less than 3% over a year. Automatic validation or manual calibration is required only once every few months. Designed to be low maintenance, with power as its only utility, the cost of ownership is the lowest on the market.
