ABSTRACT:
A method and apparatus for sampling a cryogenic liquid for determination of its molar composition involves isolating a sample of the liquid under conditions to avoid fractionation of the sample, especially isothermal conditions, removing the conditions, allowing the liquid to vaporize intact and collecting the vaporized liquid in gas form; in particular the vaporized liquid is collected in a collection vessel which may be detached from the balance of the system and transported to a site of analysis.
