Popis:	Comparative gas chromatographic applications of two new liquid crystals were investigated. The characterization of the two mesogenic compounds was performed with 1H NMR and mass spectrometry. The thermal properties were established by differential scanning calorimetry. The optical characterization of the liquid crystal was made by using polarizing optical microscopy. The chromatographic separation abilities of the mesogenic compounds were studied using fused silica capillary columns. Interesting analytical performances were obtained notably in the separation of volatile aroma compounds and derivatives phenols.
