Summary
Stabilization of polar and apolar stationary phases with nanosized particles has been demonstrated for gas chromatographic capillary columns. Mixtures of small amounts of (2–10%) of solid particles and liquids form gels, which preserve the stability of the films of stationary phases on the column walls. The stabilization effect of polar and apolar particles has been studied by determining some rheological properties of gels (flow curves, temperature dependence of yield stress values) and validated by gas chromatographic measurements using the most polar and apolar stationary phases.
