Abstract

Most of the common classes of organic compounds chromatograph normally on Superoxes. There is no tailing or adverse effect from excessively different activity different activity coefficients. Superoxes are therefore universal phases for gas chromatography. This is also expressed by a wide useful temperature range from ∼50° to ∼300°. High MW Superox‐4 has a MAOT about 20° higher than the lower MW Superox‐0.1. Several applications illustrating the versatility of Superox phases in (GC)^2^ are presented.
