This document specifies a method for the determination of hydrogen sulfide content in working field natural gas of upstream area by laser absorption spectroscopy. The analytical range expressed as mole fraction is 10 \u00d7 10\u22126<\/sup> to 20 %. The analytical range can be expanded to higher content with specific instrument requirements.<\/p>\n
