Technical specifications

The matrix below provides information to assist in selection of an Endress+Hauser analyzer for measurement of H 2 O (moisture), H 2 S (hydrogen sulfide), CO 2 (carbon dioxide), NH 3 (ammonia), C 2 H 2 (acetylene), and O 2 (oxygen) in hydrocarbon gas streams.

QF = Quenched fluorescence TDLAS = Tunable diode laser absorption spectroscopy  = Standard  = Optional
