Title: Water vapor trap and liquid separator for singlet-delta oxygen generator

Abstract: A singlet-delta oxygen generator 10 comprises a chamber 14 in which a gas stream 22 of singlet-delta oxygen, O.sub.2 (.sup.1 .DELTA.), is generated; a water vapor trap 40 to remove water vapor from the gas stream, and a liquid separator 60 downstream of the water vapor trap to separate liquid from the gas stream subsequent to removal of the water vapor. The water vapor trap comprises a liquid droplet dispersing device 42 which forms a droplet field 44 of cold liquid droplets in the chamber. The cold liquid droplets interact with and condense water vapor in the gas stream. The cold liquid is preferably hydrogen peroxide. The liquid separator comprises a baffle 62 arrangement which forms a tortuous flow path for the gas stream. Liquid in the gas stream is unable to traverse the baffles and is separated from the liquid, to produce an essentially dry gas stream for introduction into a gain generator 34 downstream of the singlet-delta oxygen generator.
