Gas Detection Technologies:
There are variety of gas detection technologies in use today for sensing or measuring the hazardous gas like H2S, Hydrocarbon etc… in oil & gas industries. Among the most commonly employed are:
• Catalytic Bead
• Metal Oxide Semiconductor (also known as “solid state”)
• Point Infrared Short Path
• Open (Long Path) Infrared
• Photoacoustic Infrared
• Electrochemical for Toxic Gas Detection
• Electrochemical for Oxygen Detection
• Thermal Conductivity
• Photoionization
• NDIR
The Operation of each Gas Detection technology summarizes as follows:
