Summary

The effect of on-column oxidation upon the efficiency of apolar gas chromatographic columns is investigated. With an unsaturated hydrocarbon liquid phase and air as carrier gas dramatic changes of column efficiency are observed. Evidence is presented that suggests that this catastrophic deterioration of column performance is due to the oxidative crosslinking of the liquid phase molecules.

Key Words
