Method by analysis by on-line chromatography for the polymerization of olefins

摘要

A method for the analysis by on-line gas phase chromatography of a gaseous phase produced by an olefin polymerization process which includes carrying out a chromatographic analysis of a gaseous phase produced by an olefin polymerization process with carrier gases containing mainly hydrogen and/or nitrogen, wherein the content of oxygen and of water of the hydrogen and the nitrogen in the carrier gases is less than 5 ppm by weight.
