TISOMIC

The TISOMIC with PA-TDL technology, Measuring the Photo Acoustic effect excited by a Tunable Diode Laser (TDL), can simultaneously measure Hydrogen Sulfide (H2S), Moisture (H2O), Carbon Dioxide (CO2), Methane (CH4) in 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
• Multi-components (H2S, CO2, H2O, CH4)
• Multi-stream with independent measuring cells
• High temperature Measurement cell (up to 80 Celsius)
• No-multi reflection mirrors → reduced sensitivity to contamination
• Continuous differential measurement in low ppm ranges and thus less sensitive to gas matrix-changes.
• Measurement on ZERO-background
• Low analyzer gas flow with low analyzer emissions
• Linear measurement signal over 3 decades
• LOW OPEX (no moving parts and low operational spare-parts requirement)
• Maintenance on demand
• Single bottle calibration

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.
