What is ISO 20676 - laser absorption spectroscopy for H2S in natural gas about? Laser absorption spectroscopy is an absorption spectroscopic method that employs a laser as the light source and measures the chemical concentration based on the detection of a variation of laser beam intensity after transmission along the optical path. ISO 20676 is a safety standard on natural gas. ISO 20676 specifies a method for the determination of hydrogen sulfide content in the working field natural gas of upstream area by laser absorption spectroscopy . The analyt...
