Gas Sensors Hydrogen Sulfide (H2S) -

Hydrogen Sulfide is flammable, naturally occurring in crude petroleum, natural gas, volcanic gas, and hot springs. It is sometimes called “sewer gas”. Biogas generators may release up to 1% hydrogen sulfide in gas streams. Any process that breaks down organic material without oxygen has the potential to create high levels of hydrogen sulfide. If heated under pressure it will explode. It is produced in …

Study on Fiber-optic Hydrogen Sulfide Gas Sensor - ScienceDirect

01/01/2014· We describe a novel fiber-optic gas sensor which hydrogen Sulfide (H2S) gas can be detected by a silver coated fiber bragg grating (FBG). The H2S sensitive material Ag can be coated on the cladding surrounding surface of FBG by conventional silver mirror reaction. The scanning electron microscope (SEM) was applied to analysis the Ag film structure before and after the interaction with …

What is a Hydrogen Sulfide (H2S) Gas Detector? | GDS Corp

14/02/2020· Hydrogen sulfide gas detectors primarily use electrochemical sensors to detect and measure parts-per-billion (‘ppb’) and parts-per-million (“ppm”) levels of H2S gas. These sensors depend on a highly reliable electrochemical reaction that occurs when H2S gas combines with specific materials used in the sensor. This reaction creates a tiny electrical current that is amplified and measured by …
