| Abstract: | Summary A packed column containing immobilized SE-54 liquid phase on pellicular silica beads ZIPAX and having a high efficiency and
high mass transfer rate has been successfully used in a two-dimensional packed+capillary column system without a cold trap.
The application of this system is demonstrated by the analysis of C6-C8 aromatic hydrocarbons and lowboiling hydrocarbons present in natural oils, and of highboiling components present in low concentrations
in a low-boiling solvent. |
