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 analytical range expressed as mole fraction is 10 × 10−6 to 20 %. The analytical range can be expanded to higher content with specific instrument requirements.
Who is ISO 20676 - laser absorption spectroscopy for H2S in natural gas for?
ISO 20676 on laser absorption spectroscopy for H2S content in natural gas is useful for:
- The oil and gas sector
- Industrial hygiene and safety professionals
- Manufacturers of laser measuring devices
- Petroleum and petrochemical industries
- Marine industries
- Upstream operators and engineers
Why should you use ISO 20676 - laser absorption spectroscopy for H2S in natural gas?
Laser absorption spectroscopy is an efficient method of determining hydrogen sulfide content in natural gas because it is an optical method. Laser absorption spectroscopy offers a stable means to analyze H2S in upstream area natural gas.
A semiconductor laser generator generates a laser beam, the laser beam goes through the sample. ISO 20676 assists the user with the analytical range of the different instruments, the different laboratories used for the suitable calibration gases to test the analytical range repeatability. ISO 20676 also assists with a total of 11 tests performed on each calibration gas, on each instrument.
ISO 20676 contributes to the safety of workers onsite at oil and gas fields, and mitigates risks for personnel, property, and the environment. This translates to end-users have access to efficiently extracted and handled products by a firm that emphasizes employee safety.
