SILVA, Denise Domingos da et al. Quantitation of linalol in the essential oil of Aniba duckei Korstermans using a new POLYH4-MD capillary column in Gas Chromatography. Quím. Nova [online]. 2003, vol.26, n.4, pp. 461-465. ISSN 1678-7064.

In the present work a polyurethane polymer derived from castor oil was used as stationary phase for capillary gas chromatography. The polymer was obtained by reaction of hydroxylated compound and isocynate (NCO), forming urethane. Columns of 7 m x 0,25 mm were then coated with this stationary phase (film thickness of 0,25 µm) using static coating method. The Grob test was also performed. Samples of essential oil of the Aniba duckei Korstermans was then analysed in POLYH4-MD capillary column in order to evaluate its chromatographic perfomance. The linalool was found to be the major component and has been used as compound of departure for many important syntheses. Results show that the experimental columns give higher resolution and can be employed for analysis of essentials oils.

Palavras-chave : POLYH4 - MD capillary column; linalool; polymer.
