Natural gas — Upstream area — Determination of hydrogen sulfide content by laser absorption spectroscopy

ISO 20676:2018 is an International Organization for Standardization (ISO) standard that specifies a method for determining the hydrogen sulfide content in natural gas from the upstream area using laser absorption spectroscopy; essentially, it outlines a standardized procedure to measure the amount of hydrogen sulfide present in raw natural gas using a laser-based detection technique.
