Abstract
Apparatus and method for sampling of a liquified gas for composition analysis. A sample flow of liquified gas is induced into the open end of an admitting tube with sufficient length immersed in the liquified gas to avoid vaporization proximate the open end and in the admitting tube. Joined to the admitting tube is a conveying tube leading to an analyzer. The flow area of the admitting tube is in the range of from about 0.01 to about 0.5 times the the flow area of the conveying tube. In the proximity of the joint is a means for heating the conveying tube so as to vaporize the sample stream. The admitting tube penetrates and extends in a conduit through which, during sampling, liquified gas flows from a vessel containing the liquified gas to be sampled. During nonsampling, the liquified gas flow is valved off and vaporized liquid from the vessel is ducted to the portion of conduit contain in the admitting tube. The vapor enters the open end of the admitting tube and flows through the conveying tube preventing the entry of ambient air and moisture.
