New stationary phases for gas chromatography based on polymers with intrinsic porosity

- Three new polymers with intrinsic porosity were evaluated as stationary phases in GC.
- Optimal kinetic plots of the stationary phases were created evaluating column performance.
- Special tests were performed evaluating thermostability of the stationary phase.
- Polymer with vicinal trimethylsilyl groups is superior to other polymers studied.

Norbornene polymers with intrinsic porosity were investigated as candidates for polymeric stationary phases in capillary GC. Kinetic and thermodynamic characteristics of the stationary phases were evaluated and turned out that only polymer with vicinal distribution of trimethylsilyl groups (polymer II) provided properties making it potential candidate for application in capillary GC. Columns with stationary phase based on polymer II demonstrated unique selectivity, moderate thermostability and efficiency better than previously studied columns with stationary phase based on poly[(1-trimethylsilyl)-1-propine].
