High speed capillary GC on 10 m × 100 μm i.d. FSOT Columns

The chromatographic performance of 10 m × 100 μm i.d. capillary columns, coated with different stationary phases, was studied. TZ‐ū plots were measured at different temperature program rates. The polarity and selectivity are strongly influenced by the temperature program rate. The analysis time depends on the capacity ratio and the selectivity factor; stationary phase selection thus is an important aspect in high speed capillary GC. A number of applications is presented and the applicability of split injection is discussed.
