Precise Hydrogen Sulfide (H2S) Gas Detection

You can get Accurate and Precise Hydrogen Sulfide (H₂S) Detection using EOC’s DOAS (Differential Optical Absorption Spectroscopy) Module.   NDIR is not effective with hydrogen sulfide because water (H₂O) interferes with the reading (H₂S and water have similar absorption bands in the IR region).  DOAS operates in the ultraviolet (UV) spectrum.

DOAS (Differential Optical Absorption Spectroscopy) is a well-established technique for gas concentration measurements using the principle of ultraviolet (UV) absorption.  It is an optical system (non-contact measurement).  DOAS uses the unique ultraviolet (UV) absorption spectrum of Hydrogen Sulfide (H₂S) to make accurate quantitative analysis and calculate its concentration value.

Other gas detection modules using TDLAS (Tunable Diode Laser Absorption Spectrometry systems include:

• Handheld Methane (CH₄) Detector C10X
• Natural Gas (Methane & Ethane) Detector
• Mini Gas Flashlight Methane (CH₄) Detector L10M
