Measuring Natural Gas Contaminants with Variations in Gas Stream Composition

For accurate and reliable measurement of gas contaminants, it is critical that the instrument is sensitive only to the contaminant itself and is not impacted by any variance in the gas stream composition.

One challenge with traditional tunable diode laser (TDL) sensors is cross-interference, where hydrocarbons in the gas absorb light along with the target contaminants, complicating the measurement. Sensi+ addresses this by using advanced spectroscopic analysis algorithms that can separate the contaminant gas absorption from the background absorption of the natural gas itself, eliminating the need for chemical scrubbers or custom instruments.
