Abstract
A method to detect, measure or remove trace amounts of condensible vapors in compressed gases. The concentration of droplets detected, measured or removed may be as low as part per trillion. The compressed gas comprising a carrier gas and condensible vapors is discharged through a critical orifice in order to condense the vapors in the form of homogeneous droplets. The droplets are either detected, or their concentration measured or removed from the expanded carrier gas.
